When prosecutors charge someone with assault using a weapon — or with force strong enough to cause serious injury, even without a weapon — the case is filed under California Penal Code § 245, not under the basic assault statute that covers bar fights and shoving matches. PC § 245 is sometimes called “aggravated assault” or “ADW” (short for assault with a deadly weapon), and it carries dramatically different consequences than a simple assault charge. State prison becomes possible. The conviction can count as a “strike” under California’s Three Strikes Law. The penalties multiply when the alleged victim is a police officer or firefighter. As a Murrieta assault with a deadly weapon attorney handling cases at the Southwest Justice Center, Nic Cocis has defended PC § 245 cases across Southwest Riverside County for over 25 years.
If you or someone in your family is facing PC § 245 charges in Murrieta, Temecula, Menifee, Lake Elsinore, Wildomar, Winchester, Canyon Lake, or French Valley, this page covers what you need to know: when assault crosses the line from simple to felony, what California law counts as a “deadly weapon,” the jail and prison exposure, the strike consequences, the heightened penalties when the alleged victim is a peace officer, and the defenses that actually work in PC § 245 cases.
When Does Assault Become a Felony in California?
California has two basic assault statutes. The difference between them is where most of these cases turn.
Simple assault under Penal Code § 240 covers attempts to use force or violence on another person without a weapon and without enough force to cause serious injury. A push during a verbal argument, a shove in a parking lot, a swung fist that did not connect — all of these are simple assault if they are charged at all. PC § 240 is a misdemeanor, with a maximum penalty of 6 months in county jail under PC § 241(a). It is not a strike. It does not require state prison.
Assault with a deadly weapon, or with force likely to cause serious injury, is the next step up — and it is charged under Penal Code § 245. This is the statute that elevates an assault into felony exposure. PC § 245 applies in two situations:
- A weapon was used. Not just guns and knives — California law treats any object as a “deadly weapon” when it is used in a way that could cause death or serious physical injury. (Covered in the next section.)
- No weapon was used, but the force itself was likely to cause serious injury. This is sometimes called “PC § 245(a)(4)” — assault by means likely to produce great bodily injury. A beating with bare hands can qualify if the force used was severe enough.
PC § 245 is what California calls a wobbler — a charge that prosecutors can file as either a misdemeanor or a felony, depending on the facts of the case, how serious the alleged force was, and the defendant’s prior record. The misdemeanor version carries up to 1 year in county jail. The felony version carries 2, 3, or 4 years in state prison — and the conviction may count as a strike.
The choice between misdemeanor and felony belongs to the prosecutor. That decision typically gets made in the weeks between arrest and the first court date. Pre-filing work by a defense attorney — character letters, witness statements, an analysis of the force actually used — can sometimes shift the charging decision toward the misdemeanor version, or away from PC § 245 entirely.
What the Prosecutor Has to Prove for Assault With a Deadly Weapon
To convict someone under PC § 245, the prosecutor has to prove all of these things beyond a reasonable doubt:
That the defendant did an act that would probably result in the use of force. The conduct does not have to actually hurt anyone — that is what makes assault different from battery. A swing of a baseball bat that missed, a knife held up in a threatening position, a punch that did not connect — all of these can support an assault charge if they meet the other elements.
That the defendant either used a deadly weapon, or used force likely to cause great bodily injury. This is the element that elevates the charge from misdemeanor PC § 240 to PC § 245 felony exposure. Either category triggers PC § 245:
- A deadly weapon was used (knife, gun, baseball bat, vehicle, bottle, brick, or other object — see the next section), OR
- No weapon was used, but the level of force itself was likely to cause serious injury. This is the “by means likely to produce great bodily injury” version, sometimes called the GBI-likely variant. A severe beating with bare hands can qualify here.
That the defendant had the present ability to apply force. This is one of the elements lay readers most often misunderstand. The defendant must have been close enough, and in a position to actually carry out the force, at the moment of the alleged assault. A threat shouted across a parking lot from 100 yards away, with no weapon and no way to actually reach the alleged victim, may fail this element. The phrase “present ability” means the capability had to exist at that moment — not in the abstract.
That the defendant acted willfully. The act has to be intentional, not accidental. A driver who lost control of a vehicle and hit someone has not committed assault — even if injury resulted — because the act was not willful.
That the defendant was aware of facts that would lead a reasonable person to realize the act would probably result in the use of force. This is similar to a reasonable-person standard. The defendant does not have to subjectively intend to cause injury, but a reasonable person in the same situation would have understood that the act was likely to result in force being applied.
What the prosecutor does not have to prove: that anyone was actually hurt. The moment any unlawful touching occurs and causes injury, the charge typically becomes battery under PC § 242 or PC § 243(d) — and PC § 245 may still apply alongside it. But the assault charge itself does not require an injury.
What Counts as a “Deadly Weapon” Under PC § 245?
California’s definition of “deadly weapon” is much broader than what most people expect. Under PC § 245, a deadly weapon is any object that is used in a way capable of producing — and likely to produce — death or great bodily injury.
Two categories matter:
Objects that are inherently deadly weapons. Firearms, knives, brass knuckles, machine guns, and similar items are deadly weapons by their nature. Their use against a person almost always supports a PC § 245 charge.
Objects that become deadly weapons depending on how they are used. This is where most contested PC § 245 cases live. Items that have been treated as deadly weapons under California law, depending on the circumstances, include:
- Baseball bats
- Tire irons
- Bricks, rocks, bottles
- Vehicles (when used to strike a person)
- Hammers and other tools
- Pens, screwdrivers, and other sharp household objects
- Boots or shoes (when used to kick someone on the ground)
- Even fists and feet, in some cases — though typically these are charged under the “force likely to produce great bodily injury” theory rather than as deadly weapons
What makes a household object a “deadly weapon” is how it was used in the specific incident. A baseball bat resting in a garage is not a weapon; the same bat swung at someone’s head is. A bottle being held while walking out of a bar is not a weapon; the same bottle smashed against a counter and used to threaten is.
The “as used” question is one of the most contested issues in PC § 245 cases — and one of the most defensible. Defense work on this point involves reconstructing the incident in detail, examining how the object was actually used, evaluating the realistic threat level, and presenting evidence that the object’s use did not meet the legal threshold for “capable of producing death or great bodily injury.”
How Many Years in Jail or Prison for Assault With a Deadly Weapon?
The exact penalty depends on which subdivision of PC § 245 applies — and the statute has several. The basic categories:
Assault with a deadly weapon (PC § 245(a)(1)). Wobbler. Misdemeanor version: up to 1 year county jail. Felony version: 2, 3, or 4 years state prison.
Assault by means likely to produce great bodily injury (PC § 245(a)(4)). Wobbler. Same penalty range as PC § 245(a)(1) — up to 1 year misdemeanor or 2, 3, or 4 years felony.
Assault with a firearm (PC § 245(a)(2)). Wobbler with elevated exposure. Misdemeanor version: 6 months to 1 year county jail. Felony version: 2, 3, or 4 years state prison. Penalties go up if the firearm is a semiautomatic.
Assault with a semiautomatic firearm (PC § 245(b)). Not a wobbler — straight felony. 3, 6, or 9 years state prison.
Assault with a machine gun, .50 BMG rifle, or assault weapon (PC § 245(a)(3)). Not a wobbler — straight felony. 4, 8, or 12 years state prison. This is the most serious of the standard PC § 245 charges that does not involve a peace officer.
For felony versions, probation is sometimes available — meaning the defendant serves the sentence on probation with conditions (typically including jail time as a condition) rather than going directly to state prison. Probation availability depends on the specific subdivision, the defendant’s prior record, and whether sentencing enhancements attach.
Base fines run from $1,000 to $10,000 depending on subdivision, before penalty assessments (which often multiply the actual amount paid).
What Happens When the Alleged Victim Is a Police Officer or Firefighter?
California treats assaults on peace officers, firefighters, and other public-safety personnel as more serious offenses. PC § 245 has separate subdivisions for these cases, with longer prison sentences:
Assault with a deadly weapon on a peace officer or firefighter (PC § 245(c)). 3, 4, or 5 years state prison. Straight felony.
Assault with a firearm on a peace officer or firefighter (PC § 245(d)(1)). 4, 6, or 8 years state prison. Straight felony.
Assault with a semiautomatic firearm on a peace officer or firefighter (PC § 245(d)(2)). 5, 7, or 9 years state prison.
Assault with a machine gun or assault weapon on a peace officer or firefighter (PC § 245(d)(3)). 6, 9, or 12 years state prison.
For any of these enhanced subdivisions to apply, two things must be true: the defendant must have known (or reasonably should have known) that the alleged victim was a peace officer or firefighter, and the officer must have been actively engaged in the duties of their position at the time. An off-duty officer in plain clothes who is not identifying themselves as law enforcement may not qualify. An officer who escalated an encounter unlawfully may not qualify. Both elements have been contested in real cases — and both can be challenged when the facts support it.
What Happens If Someone Actually Was Hurt?
PC § 245 by itself does not require an injury — but when an injury actually occurs, two additional concerns come into play.
The case may also be charged as battery. PC § 242 (simple battery) or PC § 243(d) (battery causing serious bodily injury) typically gets added alongside the PC § 245 count. For deeper coverage of when battery becomes a felony in injury cases, see the firm’s PC § 243(d) battery with serious bodily injury cornerstone.
Sentence enhancement for great bodily injury. When the injury qualifies as “great bodily injury” — significant or substantial physical injury, more than minor cuts and bruises — Penal Code § 12022.7 adds 3 years consecutive to the underlying felony sentence. Conditions that have been treated as great bodily injury include broken bones, lacerations requiring stitches, internal injuries, concussions causing lasting effects, and prolonged hospital stays.
The GBI enhancement matters in a second way: it transforms PC § 245(a)(4) (the “by means likely to produce great bodily injury” subdivision) from a non-strike offense into a strike. Without the enhancement, PC § 245(a)(4) by itself is not a strike. With the GBI enhancement attached because injury actually occurred, the conviction does count as a strike.
Defense work on the GBI question — challenging whether the injury legally qualifies as great bodily injury rather than ordinary bodily injury — can remove the 3-year enhancement and change the strike characterization of the case.
Will an Assault With a Deadly Weapon Conviction Count as a Strike?
For most PC § 245 felony convictions, yes — and this is one of the most important issues in any PC § 245 case.
California’s Three Strikes Law treats certain felonies as “serious felonies” or “violent felonies.” A conviction in either category becomes a “strike prior” on the defendant’s record, with three consequences for any future felony case:
- The current sentence is unaffected by being a strike (the doubling effect applies to future cases)
- If the defendant later picks up another felony case, the prior strike doubles the new sentence
- Two or more strike priors trigger 25-to-life under PC § 667(e)(2)
Which PC § 245 convictions count as strikes:
- PC § 245(a)(1) felony with a deadly weapon — strike on its own, no enhancement needed (serious felony under PC § 1192.7(c)(31))
- PC § 245(a)(2) felony with a firearm — strike on its own (serious felony)
- PC § 245(a)(3) felony with machine gun/assault weapon — strike on its own
- PC § 245(a)(4) felony by means likely to produce GBI — not a strike unless the GBI enhancement actually attaches (i.e., the alleged victim was actually seriously injured)
- PC § 245(b), (c), (d) variants involving firearms, peace officers, or both — all strikes
- Misdemeanor versions of any PC § 245 subdivision — not strikes
This is the single most important reason to negotiate the charging tier carefully in any PC § 245 case. The difference between a felony PC § 245(a)(1) conviction and a misdemeanor PC § 245(a)(1) conviction is not just the immediate sentence — it is the strike consequence that follows the defendant for life. A felony reduction to a misdemeanor under PC § 17(b), where available, eliminates the strike. So does a charging-tier reduction from PC § 245(a)(1) (deadly weapon) to PC § 245(a)(4) without GBI (force-only).
For defendants who already have a strike prior on their record, the calculation gets sharper still. A second strike doubles any future felony sentence. Negotiating the PC § 245 case to a non-strike disposition is often the central strategic concern.
Self-Defense and Other Defenses in PC § 245 Cases
PC § 245 cases have more viable defenses than many felony charges, largely because the elements involve subjective evaluations (what counts as a deadly weapon, what counts as force likely to cause GBI, what the defendant intended) that are genuinely contestable.
Self-defense and defense of others. California law allows the use of force — including potentially deadly force — when a person reasonably believes they are in imminent danger of bodily harm, and the force used is proportional to the threat. Self-defense is a complete defense to PC § 245. The defense applies whether the defendant was protecting themselves or protecting another person. Investigation of who initiated the encounter, whether the defendant retreated when able, and what the defendant reasonably perceived at the moment of force is central.
The object was not a deadly weapon as used. Where the alleged weapon was an ordinary household object (a bottle, a phone, a piece of furniture) and the actual use did not meet the threshold for “capable of producing death or great bodily injury,” the deadly-weapon element can fail. Bringing the case down to misdemeanor simple assault under PC § 240 — or eliminating it entirely — becomes possible.
The force used was not likely to cause great bodily injury. When the case is charged under the force-only theory (PC § 245(a)(4)), the prosecution has to prove the level of force used was likely to produce significant injury. Where the force was limited, where no injury actually occurred, or where the contact was incidental, this element can fail.
No present ability. Where the alleged threat occurred at a distance, without a weapon capable of bridging the distance, the present-ability element can fail. The defendant must have had the actual ability to cause harm at the moment, not just a stated intention.
No willfulness. The act has to be intentional. Accidents do not support PC § 245 charges, even when injury occurs.
Mistaken identity. PC § 245 cases sometimes involve multiple people in chaotic situations — bar fights, party brawls, group confrontations. Identification of the defendant as the actual person who used the force can be contestable when no clear witness, video, or physical evidence establishes the identity.
Constitutional challenges. Where the arrest was made without probable cause, where statements were taken in violation of Miranda rights, or where evidence was obtained through an unlawful search, suppression motions under California criminal procedure can eliminate critical evidence.
Charging-tier negotiation. Even when the elements are met, negotiation focuses on which subdivision applies, whether the charge is filed as a misdemeanor or felony, and whether sentencing enhancements attach. Resolution from a charged PC § 245(a)(1) felony with strike consequences down to a misdemeanor PC § 245(a)(1) — or to PC § 240 simple assault without strike exposure — can be the most consequential outcome in the case.

The First Decisions That Shape a PC § 245 Case
A PC § 245 case in Murrieta, Temecula, or Menifee is decided in three windows that close quickly.
The window before charges are filed. Before the District Attorney’s Southwest Office files the formal complaint, the case file consists of the police report, witness statements, photographs of any alleged injuries or weapons, and any video evidence. Defense work during this window — submitting counter-evidence, witness statements supporting self-defense, an analysis showing the deadly-weapon characterization is overstated — can produce three favorable outcomes: filing as a misdemeanor rather than a felony, filing under PC § 245(a)(4) rather than PC § 245(a)(1) (avoiding the automatic strike), or filing under PC § 240 simple assault rather than PC § 245 at all. After the complaint is filed, repositioning becomes harder.
The preliminary hearing window. For felony filings, the preliminary hearing is the defense’s first opportunity to challenge the prosecution’s evidence on the record. Cross-examination of the alleged victim, eyewitnesses, the investigating officer, and any medical witness on the GBI characterization develops the trial record. A successful motion after the preliminary hearing can dismiss the case or reduce charges.
The disposition window. Plea negotiations focus on charging-tier reduction (felony to misdemeanor wobbler reduction under PC § 17(b)), avoiding strike characterization where possible, and planning for post-conviction relief — whether the conviction will be eligible for expungement, whether the strike consequences attach for any future case, and how the conviction will affect immigration status, professional licensing, or firearm rights.

Why a Murrieta Assault With a Deadly Weapon Attorney Matters Early in a PC § 245 Case
A PC § 245 case is not a routine criminal case. Base exposure includes state prison when filed as a felony. Sentence enhancements for great bodily injury, firearm use, and peace officer victim status can dramatically extend that exposure. And the strike consequence — the most important long-term issue in most PC § 245 cases — attaches at the moment of conviction and follows the defendant for life.
The decisions that shape the outcome happen in days and weeks, not months:
Within days of arrest. Witnesses must be located before memories fade or contact information becomes stale. The alleged victim’s medical records, where injury is claimed, must be subpoenaed before they are routinely destroyed. Photographs of the scene, any weapons recovered, and the defendant’s own physical condition at arrest can be critical evidence of self-defense — and these have to be preserved early.
Before the felony complaint is filed. Pre-filing work with the District Attorney’s Southwest Office can shift the charging tier and the strike characterization. After the complaint is filed, the case has a docket number, an assigned deputy DA, and an institutional momentum that is harder to redirect.
Before any plea. The strike characterization attaches with the plea. A felony PC § 245(a)(1) plea is a strike conviction. A misdemeanor reduction or a reduction to PC § 245(a)(4) without GBI eliminates the strike. Understanding which option is available — and which is achievable through negotiation — is critical before any plea is entered.
Throughout the case. Self-defense investigation, scene reconstruction, the deadly-weapon characterization challenge, and the GBI characterization challenge all require sustained defense work that cannot be done in a single hearing.
Anyone arrested under PC § 245 in Southwest Riverside County — Murrieta, Temecula, Menifee, Lake Elsinore, Wildomar, Winchester, Canyon Lake, or French Valley — should preserve every document, photograph, and message related to the incident, identify and contact potential witnesses before they disperse, and contact a Murrieta assault with a deadly weapon attorney before any plea is entered.
