What to Do If You or Someone You Know Is Under Homicide Investigation in Oakland

Here’s what to do if someone you know is under a homicide investigation.

• Stay silent. The Fifth Amendment gives your loved one the right to say nothing, and anything said to Oakland PD can be used against them.
• Do not agree to interviews. Detectives are trained to get statements before an attorney steps in. Wait.
• Get an attorney early. Before charges are even filed, a defense attorney can preserve evidence, contact witnesses, and sometimes speak to the Alameda County DA to shape what happens next.
• Stay off social media. Posts get pulled into cases.
• Do not contact witnesses. It can look like tampering, even when it isn’t.

If arrested, they need counsel now. If only a “person of interest,” early legal help still matters.

What Is the Difference Between Murder and Manslaughter in California?

The main difference between murder and manslaughter in California is intent. 

Murder generally means prosecutors believe someone acted with malice, meaning they intended to kill or acted with a conscious disregard for human life. Manslaughter generally means a death happened unlawfully, but without the same level of malice required for murder.

California recognizes different forms of manslaughter, including voluntary manslaughter, involuntary manslaughter, and vehicular manslaughter. Voluntary manslaughter may apply when the death happened during a sudden quarrel, in the heat of passion, or under imperfect self-defense. 

For families in Oakland, the exact charge matters. A defense lawyer may examine whether the prosecution can prove intent, malice, self-defense issues, and whether the facts support murder at all. In some cases, the fight is not only about guilt or innocence, but also about whether the charge should be reduced from murder to manslaughter.

Our Homicide Defense Process in Oakland

1. Confidential Consultation

We start by listening. We learn the charges, the facts, and what happened, and we answer your questions straight, including the cost conversation.

2. Pre-Filing Intervention

If charges are not filed yet, we can step in early and push to shape or stop them before the DA locks in a decision.

3. Independent Investigation

We do not take the police version at face value. We review the evidence ourselves, examine the scene, and track down witnesses the state missed.

4. Legal Motions Strategy

We look for constitutional violations, weak probable cause, and evidence that should be thrown out, then file motions to suppress it.

5. Bail and Detention Strategy

At arraignment in Alameda County Superior Court at the Rene C. Davidson Courthouse, we fight for the best release terms possible for your loved one.

6. Preliminary Hearing Defense

We challenge the state’s case at the prelim, where the DA has to show they have enough to move forward.

7. Negotiation From Trial Readiness

Prosecutors deal differently when they know we are ready to try the case. That readiness is our leverage.

8. Trial Preparation

We build for jury selection, forensic analysis, and witnesses who can hold up under cross-examination.

9. Verdict and Post-Trial Options

After trial, we pursue appeals, writs, and SB 1437 petitions where they apply.

Frequently Asked Questions About Homicide Defense

What is the felony murder rule and how did SB 1437 change it in California?

The old felony murder rule let prosecutors charge someone with murder if a death happened during a felony, even if that person never intended to kill anyone. California’s SB 1437 changed this in 2019. Now, a person generally cannot be convicted of murder just for taking part in an underlying felony unless they actually killed, intended to kill, or were a major participant acting with reckless indifference to life. 

Can I be charged with murder in California even if I did not pull the trigger?

Yes, and this surprises many families. Under aiding and abetting and conspiracy laws, someone can face a murder charge for helping plan or carry out a crime that led to a death. But SB 1437 narrowed how far this reaches, so not everyone present at a scene can be convicted of murder anymore. The facts of what your family member actually did and intended matter enormously here. 

Should my family member talk to the police if they are a suspect in a homicide investigation in Oakland?

No. Anyone who is a suspect should not answer questions without a lawyer present. Police are allowed to mislead people during questioning, and even innocent explanations can be twisted and used later. Your family member has the right to stay silent and the right to an attorney, and using both is not an admission of guilt. 

What happens at a homicide arraignment in Alameda County, and how fast does it move?

The arraignment is the first court appearance, usually held at the Rene C. Davidson Courthouse in downtown Oakland. This is where the charges are formally read, a plea is entered, and the judge addresses bail or custody. It happens fast, often within a couple of days of arrest, which is why calling an attorney right away matters. 

Can a homicide charge be reduced or dismissed before trial?

Yes, it happens more often than families expect. Charges can be reduced when the evidence is weak, when witnesses are unreliable, or when the facts support a lesser offense like manslaughter. Cases can be dismissed when a search was illegal, when key evidence falls apart, or when the prosecution cannot prove intent. 

What is special circumstances murder, and what does LWOP mean?

Special circumstances murder involves specific aggravating factors under California law, such as murder during a robbery or the killing of a witness. When these apply, the punishment can be life without the possibility of parole, which is what LWOP means, or in rare cases the death penalty. Because the stakes are the highest possible, these cases demand serious, experienced defense. 

How does a defense attorney actually investigate a homicide case?

A defense attorney does not just wait for the prosecution’s file. The team reviews police reports, body camera footage, forensic evidence, and 911 calls, then looks for gaps and mistakes. They interview witnesses the police ignored, examine the crime scene, and sometimes bring in independent analysts to challenge the state’s version of events. 

What is the difference between attempted murder and assault with a deadly weapon?

Attempted murder means the person took a direct step toward killing someone and intended to kill. Assault with a deadly weapon means using a weapon in a way that could cause serious harm, but without proof of intent to kill. The difference matters because attempted murder carries much heavier prison time.
