The U.S law has several definitions for all kinds of murder and homicide offenses. Some of them are more serious than others. Involuntary manslaughter is the unintentional killing of another person due to negligence or any other unlawful act. The perpetrator does not have the intention to kill the victim.
There are several differences between involuntary manslaughter and murder. Though both result in the killing of another person, the basic difference is that of intention. First and Second degree murders charges establish that the defendant had clear intention to kill the victim. On the other hand, manslaughter is the unintentional killing of another person. However, if the manslaughter occurred while the defendant was committed another serious felony, it could be considered as a first or second degree murder. Most cases involving manslaughter charges include car accidents and people hitting pedestrians without the intention to kill them.
