Are you facing allegations of murder or manslaughter?

A homicide offense is among the most heavily punished crimes in the country. If you have been accused of killing another person, you could be facing charges of murder or manslaughter. It is extremely important that you obtain representation from a St. Louis criminal defense attorney at JMH Law Firm, LLC, because Missouri laws bring very harsh penalties against those convicted.

Our firm has defended clients in more than 100 criminal jury cases in our 60 years of practice, so you can rest assured that we are well prepared to handle your case.

Murder

An individual can be charged with murder in the first degree if they "knowingly cause the death of another person after deliberation upon the matter." The state must be able to prove that the act was premeditated. Murder in the first degree is considered a Class A felony and is punishable by death or life imprisonment without the eligibility for probation or parole.

Murder in the second degree occurs if an individual "knowingly causes the death of another person or, with the purpose of causing physical injury to another person, causes the death of another person." Murder in the second degree is also considered a Class A felony, but is instead punishable by 10 to 60 years in prison or life imprisonment without the eligibility for probation or parole.

Manslaughter

Manslaughter, on the other hand, may be prosecuted if an individual kills a person without forethought and with provocation. One would be guilty of voluntary manslaughter if they cause another person's death under the influence of sudden passion or knowingly assist another with suicide—also known as euthanasia. Voluntary manslaughter is a Class B felony and punishable by 5 to 15 years in prison.

Involuntary manslaughter is when an individual recklessly causes another person's death or negligently causes another person's death while operating a motor vehicle while intoxicated. Under these circumstances, the killing is unintentional. Involuntary manslaughter is a Class D felony, punishable by up to 4 years in prison.

Possible Defenses

Below are a few common defenses available for defendants charged with homicide:

Justifiable homicide is excused by the law. If proven, it may allow a defendant to get off with no punishment or sentencing given.

  • Self-defense: If the defendant acted out of the honest and reasonable belief that the homicide was necessary for self-defense, they may be able to get off. Usually, this means not initiating the violence and using an equal amount of force in responding to the aggressor.
  • Defense of property: It usually must be proven that the intruder or trespasser threatened the life of the property owner.
  • Crime prevention: If the defendant commits a killing while preventing a crime, it can be a defense if it is proven that the intervention was necessary.

Inability to intentionally kill is when a defendant is unable to understand that they have a duty not to take a life. This defense may not excuse a homicide, but it can reduce charges to voluntary or involuntary manslaughter.

  • Insanity: It must be proven that the defendant is not mentally sound and that they lacked the required mental state for homicide.
  • Intoxication: This type of defense is usually used to reduce murder charges to less serious charges.

Reasonable mistake: In order to have the mental state to kill, the defendant must have the knowledge that the killing was illegal and unjustified. A reasonable mistake means that the defendant lacks that knowledge.

  • Mistakes of fact: When a defendant mistakenly believes their life is at stake, which helps support self-defense, it can be a mistake of fact.
  • Entrapment: If a law enforcement agent or officer encourages a person to commit a homicide, it is entrapment.

  • I was driving pretty quickly in a work zone. What I thought would turn into a night in jail ended up as illegal parking and completing a DIP program virtually from home. Though every situation and outcome is different, the ease of the process alone was worth coming to JMH. Very professional and supremely helpful across the board. Thank you, JMH! Will refer you as often as I can!

  • Joe helped me with a speeding ticket so I didn’t get any points on my license. Easy to work with and managed everything via phone/email with me, which was so convenient. He walked me through what to expect and the costs so I had no surprises. Highly recommend!

    - Katie H.
  • Had my first interaction with Joe this morning to take a look at a traffic ticket for my son who was at fault in a minor accident that we settled outside of insurance. Joe was easy to work with over the phone, and he made the process simple for us. He went above and beyond to get the case resolved in less than 3 hours. Even better was the unexpected surprise that Joe was able to negotiate to get my son's traffic citation completely dropped like it never happened! Never thought that was possible and now I won't hesitate to call Joe again if my family is ever needing an attorney in the future. Highly recommended.

    - Jonathan D.
  • I called around to a few agencies when I finally received my appearance in court letter and Joseph Harvath was by far the nicest attorney I spoke with. Exceptional customer service. He wasn’t afraid to educate me on the process either, which was far more than what the others I spoke with were willing to do. JMH took all the information needed from me right then and there on the initial call. Received a letter a week later with a new court date, that same day I received notification that it was all taken care of. I highly recommend if you want to fight any traffic violation almost hassle free.
