involuntary manslaughter
Causing someone's death without intent to kill, through reckless or negligent conduct.
Plain English
Involuntary manslaughter is when someone dies as a result of the defendant's actions, but the defendant didn't mean to kill them and didn't intend to cause serious harm. Instead, the death results from recklessness (taking a serious risk) or criminal negligence (failing to follow a legal duty). It's less serious than murder because there's no intent to kill, but more serious than a simple accident because the defendant's conduct was dangerously irresponsible.
Example
A driver who is texting while driving and hits a pedestrian, killing them, can be charged with involuntary manslaughter. The driver didn't intend to kill anyone, but the reckless act of texting while driving caused the death.
Used in a sentence
“The defendant was convicted of involuntary manslaughter after his negligent operation of heavy machinery resulted in a coworker's death.”
