Depraved heart murder

Depraved heart murder is an American legal term for when an action that demonstrates a "callous disregard for human life" results in death. In most states, depraved heart killings constitute either second-degree murder or first-degree manslaughter.

Examples might be:

• Piloting a motorboat at high speed through a crowded swimming area on a lake.
• Shooting a gun randomly at a bus with passengers aboard.
• Speeding in a car past the right hand side of a school bus that is unloading children.

If no death results, such acts would generally be defined as reckless endangerment and possibly other crimes, such as assault.
