Here's a hypothetical from a story I'm working on. A guy gets shot by someone who maliciously intends to murder him (unfortunate). The shot does not kill the victim. He runs off and stumbles into a highway where he is almost hit by a truck (more unfortunate). The near miss scares the guy. He has a heart attack and dies (most unfortunate).
The shooter meant to murder the man. The victim was running away from his attacker.
Can the shooter be charged with murder or manslaughter or some other crime?
