At The Law Offices of Frances Prizzia, our Orange County assault defense lawyer knows that distinguishing between attempted murder and aggravated assault is crucial in criminal matters. In California, over 12,000 individuals were arrested for aggravated assault in 2023, while attempted murder charges are reserved for the most serious criminal homicides.
Both are felonies, but the key difference often hinges on intent. A conviction for attempted first-degree murder or attempted second-degree murder can lead to decades in state prison. At the same time, aggravated assault may carry a shorter prison sentence depending on the use of a deadly weapon. This guide explains the legal definitions, potential penalties, and defense strategies, showing why you need experienced criminal defense attorneys to protect your rights and freedom.
Intent is the central factor that separates attempted murder from aggravated assault. While both charges involve violent acts and the use of a weapon, prosecutors must prove that the defendant acted with a specific intent to kill for attempted murder. Aggravated assault may involve a dangerous weapon or firearm, but does not necessarily require proof that the defendant wanted to cause death.
The difference in intent affects whether the case is considered attempted felony murder, assault with intent to murder, or second-degree murder. We work closely with clients to examine the evidence and craft a defense strategy that focuses on challenging the alleged intent and reducing potential prison sentences.
Specific intent means the defendant consciously intended to cause the death of another person. In attempted murder cases, law enforcement officers and prosecutors look at actions, words, and circumstances to infer this intent. Using a firearm, a deadly weapon, or committing assault with the intent to murder can all support the charge.
Examples include aggravated attempted murder during residential burglary, robbery with a deadly weapon, or felonious murder attempts. We evaluate every piece of evidence to determine whether the prosecution can prove specific intent beyond a reasonable doubt, thereby protecting clients from life sentences or decades in state prison.
Aggravated assault does not always require an intent to kill. Instead, the prosecution may need only to show a general intent to commit a violent act or an intent to cause serious bodily injury. This can involve the use of a weapon, firearm, or dangerous weapon that could cause bodily injury or serious bodily harm.
Examples include assault during commercial burglary or residential burglary, or assaults with altered firearm serial numbers. We help clients challenge claims of intent and show that the alleged act may not rise to attempted murder, potentially reducing the severity of the prison sentence.

At The Law Offices of Frances Prizzia, we know that understanding the legal definitions is essential in criminal matters. California's Penal Code provides specific definitions for attempted murder and aggravated assault, which form the basis of the charges. These definitions determine how prosecutors pursue criminal attempts and what penalties a defendant may face.
The distinction between the two crimes is crucial in the criminal justice system, as it impacts potential prison sentences, fines, and eligibility for strike penalties. Our criminal defense lawyers review every charge carefully to build a defense strategy tailored to the client’s situation.
Attempted murder under California law is a willful, deliberate, and premeditated attempt to kill another human being. "Willful" means the act was intentional, "deliberate" means carefully considered, and "premeditated" means planned ahead of time. Prosecutors must prove all three elements to secure a conviction. Evidence can include the use of a weapon, words expressing intent, or actions showing planning. We help clients challenge whether the prosecution can truly prove a criminal attempt to commit murder and protect them from life sentences or decades in state prison.
Aggravated assault occurs when a person commits assault with a deadly weapon or uses force likely to cause great bodily injury. Actual bodily injury is not required to meet the charge. Examples include using a firearm, knife, or other dangerous weapon during a robbery or residential burglary. The charge can arise even if no one is physically hurt, as long as the potential for serious bodily harm exists. We work with clients to challenge the evidence, demonstrate a lack of intent, and reduce potential prison time through a robust criminal defense strategy.
The difference in intent between attempted murder and aggravated assault leads to very different consequences. Attempted murder charges often carry life sentences, whereas aggravated assault penalties, while serious, are generally shorter. Understanding these differences is critical for clients facing charges in the criminal justice system. Our criminal defense lawyers help evaluate the penalties, consider strike implications, and work to protect clients from the maximum prison time. Below is a comparison of typical sentences for each charge:
| Crime | Typical Prison Time | Additional Notes |
|---|---|---|
| Attempted Murder | 5, 7, or 9 years to life | Strike under the Three Strikes law, enhanced if the victim is a peace officer |
| Aggravated Assault | 2, 3, or 4 years | May count as a strike depending on circumstances, plus fines |
Attempted murder carries severe penalties, including 5, 7, or 9 years to life in state prison. It is considered a “strike” under California's Three Strikes law. Penalties are enhanced if the crime involved premeditation, a firearm, or if the victim was a peace officer.
Additional considerations include:
We help clients explore every defense and negotiate strategies to reduce exposure to life sentences.
Aggravated assault is serious but generally carries less time than attempted murder. Typical penalties include 2, 3, or 4 years in state prison, as well as substantial fines. The charge may count as a strike depending on the use of a deadly weapon or the severity of the assault.
Additional considerations include:
Our criminal defense lawyers carefully analyze each case to limit potential prison time and fines and protect clients within the criminal justice system.

Our criminal defense lawyers know that the best strategy depends on the charge. Each case is different, and the defense must target the elements the prosecution must prove. Attempted murder requires showing specific intent to kill, while aggravated assault requires showing use of force likely to cause serious bodily injury. By identifying weaknesses in the evidence, we work to reduce potential prison time and protect clients’ rights. A tailored approach enables us to achieve the best possible outcomes within the criminal justice system.
Defending against attempted murder involves questioning the alleged intent to kill. Our criminal defense lawyers explore whether the act was premeditated or happened in the heat of passion. Other defenses include mistaken identity or arguing that the act was only an assault without specific intent to kill. We also review whether any evidence of criminal attempt is credible or legally obtained. By focusing on intent, we aim to reduce charges or penalties and protect clients from life sentences or involvement with prison personnel.
For aggravated assault charges, defenses focus on the nature of the act and the weapon used. Common defenses include self-defense or defense of others. We also examine whether a deadly weapon was truly involved or if the force used was unlikely to cause great bodily injury. False accusations or unreliable witness statements are also key points we investigate. Our criminal defense lawyers use these strategies to challenge the prosecution and minimize potential prison sentences.

At The Law Offices of Frances Prizzia, we know that early intervention by skilled criminal defense lawyers can make a difference in whether charges are filed as attempted murder or aggravated assault. Acting quickly enables us to gather evidence, interview witnesses, and construct a robust trial defense. Our experience negotiating with prosecutors often helps reduce potential prison sentences and protect the client’s future.
Key advantages of working with us include:
Can aggravated assault charges be upgraded to attempted murder?
Yes. If further investigation reveals evidence of intent to kill, prosecutors can amend the charges to attempted murder, which carries far more severe prison sentences.
What is a "wobbler" offense in this context?
Aggravated assault (PC 245) is often a "wobbler," meaning it can be charged as either a felony or a misdemeanor depending on the facts and the defendant's criminal record.
Is it possible to get an attempted murder charge reduced
Yes. With an aggressive defense, charges can sometimes be reduced to aggravated assault, which carries significantly lower prison sentences and fines.
What does "great bodily injury” mean legally?
It refers to significant physical injury, more severe than minor harm. Prosecutors must prove this to pursue certain enhancements in aggravated assault or assault with intent to murder cases.
How does self-defense apply to these charges?
Self-defense is a complete defense to both attempted murder and aggravated assault. You have the right to use reasonable force to protect yourself or others from imminent harm.
What should I do if I am under investigation for either charge?
Exercise your right to remain silent and contact our criminal defense lawyers immediately. Do not speak to law enforcement officers without your attorney present.

Both attempted murder and aggravated assault charges have life-altering consequences, including long prison sentences and permanent criminal records. At The Law Offices of Frances Prizzia, we provide sophisticated and relentless defense strategies to protect your future.
