What is involuntary manslaughter? A law professor explains the charge facing Alec Baldwin for ‘Rust’ shooting death

As a professor of law, my job is to understand the nuance of the U.S. legal system. Involuntary manslaughter occurs when a person unintentionally, but still unlawfully, kills another person. And a prosecutor will need to show the unlawful nature of either Baldwin’s or Gutiérrez-Reed’s actions to get a conviction in this case.

A reckless or negligent accident

To convict someone of involuntary manslaughter, a prosecutor has to prove that the defendant acted either recklessly or with criminal negligence.

To prove someone acted recklessly, a prosecutor has to show that the defendant was aware of the risk they were creating with their actions – like a drunk driver crashing into a car and killing a baby and her parents. In contrast, the charge of criminal negligence is filed when a defendant is not aware of the risk, but a reasonable person in the position of the defendant would have been aware of the risk. For example, if someone rents out an apartment without smoke detectors and there is a fire that kills the occupants, the owner of the apartment could be charged with involuntary manslaughter.

The question for a potential jury is whether Baldwin was guilty of either reckless or criminally negligent actions that resulted in the death of Halyna Hutchins, the cinematographer on the “Rust” set.

The prosecutor is alleging that Baldwin had a duty to ensure that the gun and the ammunition he used were properly checked and that without doing that check himself, Baldwin should never have pointed the gun at anyone. Although that is what the prosecutor is claiming, a complicating factor is that there was another person, an on-set safety person responsible for the weapons and ammunition.

To convict Baldwin of manslaughter – assuming the case goes to trial – the prosecutor will have to convince a jury of two things. First, that Baldwin could not reasonably rely on Gutiérrez-Reed to do her job and ensure that the gun did not have any live ammunition in it. And second, that Baldwin acted recklessly, or at least with criminal negligence, by not checking the gun and the ammunition himself before pointing the gun at the person he killed.
