Assault With a Deadly Weapon Defense in Marin County

Assault with a deadly weapon is a serious California charge. Under Penal Code section 245, the case can be filed as a misdemeanor or a felony depending on the weapon, injuries, and other facts. Marin County courts treat these allegations carefully because the potential jail or prison exposure is significant.

If you were arrested or charged, the next steps are to understand what the prosecution must prove, protect any court dates or release conditions, and get advice tied to the specific evidence in your case.

What to do after an ADW arrest

1. Read every document you received and note the court date and any release conditions.
2. Follow any order that limits contact with the alleged victim or witnesses.
3. Preserve evidence: messages, photos, medical records, videos, and witness names.
4. Avoid discussing the facts on social media or in texts that could become evidence.
5. Get case-specific advice before talking with investigators about the incident.

California Penal Code section 245(a)(1) covers assault on another person with a deadly weapon or instrument other than a firearm. A “deadly weapon” is not limited to knives. An object can qualify when it is used in a way that is capable of producing great bodily injury or death. Examples can include a bat, bottle, vehicle, or other instrument, depending on how it was used.

Key issues in many ADW cases include:

• Whether an assault occurred under California law
• Whether a deadly weapon or instrument was used
• Whether the act was willful
• Whether the facts support misdemeanor or felony charging

ADW is generally treated as a general-intent offense: the prosecution typically focuses on whether you willfully committed the charged act, not on a separate specific intent to cause a particular injury. Accidental conduct and disputed weapon characterizations are often central to the defense review.

Assault with a deadly weapon is often a wobbler in California. That means prosecutors may charge it as a misdemeanor or a felony based on the weapon, injuries, prior record, and whether the alleged victim is in a protected class such as a peace officer.

As a general guide under current California law:

• Misdemeanor ADW (non-firearm): up to one year in county jail and a fine of up to $1,000
• Felony ADW (deadly weapon other than a firearm): state prison exposure that can reach up to four years, plus fines that can reach $10,000
• Firearm-related assault paths: separate subdivisions of section 245 can carry higher prison exposure, including longer terms when certain firearms are involved

The exact range depends on the charged subdivision, enhancements, priors, and the proof available. A conviction can also affect probation terms, firearm rights, employment, licensing, and immigration questions. Treat the allegation as serious even when the facts feel disputed or incomplete.

An ADW charge can change quickly from a fight or confrontation narrative into a felony exposure case. Kevin Heaney defends people facing assault with a deadly weapon and related charges in Marin County and reviews the reports, alleged weapon, injuries, and legal elements the prosecution must prove.

Defense issues that may apply, depending on the evidence, include:

• Self-defense or defense of others
• No assault, or no deadly weapon/instrument under the facts
• False accusation, mistaken identity, or credibility problems
• Insufficient evidence to prove each required element

Not every issue applies in every case. An attorney can explain which arguments are realistic based on the videos, injuries, statements, and physical evidence.
