Can murder be committed by omission?

Yes, murder can be committed by omission in certain circumstances, particularly when there is a legal duty to act. If an individual fails to intervene or provide necessary assistance, leading to another person's death, they may be held criminally liable for murder or manslaughter. This typically applies in situations where there is a clear obligation to act, such as a caregiver failing to provide essential care to a dependent. The specifics can vary by jurisdiction and the details of each case.
