What to Do Next If You’ve Been Charged With Involuntary Manslaughter in California

August 17, 2026 | Nafiz M. Ahmed

An involuntary manslaughter charge can put you in a felony case even though prosecutors are not accusing you of intending to kill anyone. What you do after being arrested or charged can also affect what evidence is available and how the case develops.

If you are facing involuntary manslaughter charges in San Jose, California, avoid making rushed decisions about the allegations. Understanding the charge, protecting your rights, and preserving information that may matter to your defense are important first steps.

Understand What California Considers Involuntary Manslaughter

California Penal Code § 192(b) defines involuntary manslaughter as an unlawful killing without malice that occurs while committing an unlawful act that is not a felony or while performing a lawful act that might cause death in an unlawful manner or without due caution and circumspection.

The statute does not cover deaths caused while driving a vehicle; California addresses those cases separately under its vehicular manslaughter laws.

Involuntary manslaughter does not require an intent to kill. Depending on the theory of the case, prosecutors may instead need to establish criminal negligence and causation.

Do Not Discuss the Case With Other People

After an arrest, you may want to explain what happened to friends, relatives, coworkers, or people connected to the person who died. Those conversations can create statements that investigators or prosecutors may later try to use.

Be particularly careful with:

Text messages and direct messages
Social media posts or comments
Emails
Recorded jail or telephone calls
Conversations with witnesses or members of the other person’s family

Trying to explain that an incident was accidental may seem harmless, but a statement can sound very different when viewed outside its original context. You can decline to answer law enforcement questions and speak with a criminal defense attorney before deciding whether to make a statement.

Involuntary manslaughter cases can depend heavily on what happened immediately before, during, and after the death. Evidence that gives context to those events may become important as the facts are investigated.

Depending on the situation, potentially relevant material may include:

Photographs or videos of the location
Text messages, emails, or other communications
Names and contact information for witnesses
Medical or emergency-response records
Surveillance or cellphone footage
Documents showing what occurred before or after the incident

Do not alter, delete, discard, or destroy possible evidence. Instead, identify what exists so it can be properly preserved and reviewed.

Ask Whether Technical or Expert Evidence Could Affect the Case

Not every involuntary manslaughter case can be understood from witness statements alone. Questions about how a death occurred, what created the danger, or whether a person’s actions actually caused the death may involve technical evidence.

Depending on the allegations, that evidence could involve:

Medical records or autopsy findings
Toxicology results
Accident or scene reconstruction
Workplace or equipment records
Video timing and digital evidence
Specialized medical or scientific opinions

This type of evidence can matter when the prosecution’s version of events depends on assumptions about causation or criminal negligence. Identifying those issues early can help determine what records should be preserved and what parts of the government’s theory need closer examination.

Learn What Penalties You Could Face

Involuntary manslaughter is a felony in California. The offense is punishable by a term of two, three, or four years. These penalties depend on the facts and circumstances and are outlined in Penal Code § 1170(h).

California sentencing law also governs how a court selects among prescribed sentencing terms and permits consideration of aggravating and mitigating circumstances.

A felony conviction can affect more than the period of incarceration. Before making major decisions about a case, it is important to understand both the immediate charge and the consequences that may follow a conviction.

Start Examining the Prosecution’s Case Early

Being charged with involuntary manslaughter does not establish guilt. The prosecution still has to prove each required element beyond a reasonable doubt.

A defense may focus on issues such as:

Whether the conduct amounted to criminal negligence
Whether the alleged unlawful act occurred
Whether the defendant’s conduct caused the death
Whether witness accounts are reliable
Whether physical or digital evidence contradicts the prosecution’s theory
Whether evidence was lawfully obtained

Early review can be especially valuable when evidence is temporary. Surveillance recordings may be overwritten, physical conditions may change, and witnesses can forget details as time passes.
