Help with a death

[Griffin]

So I'm writing a play and I need a character death to have happened already in a specific way and I wanted to tap you guys's brains.

Jessie, main character, has killed his best friend Dave. Through some sort of inaction on Jessie's part, Dave died. Jessie then covered it up to make it look accidental. Drugs and alcohol are not out of the question. Any ideas you got, send 'em my way. Anything could spark another idea.

Thanks friends!

Jessie kills him, but purely through inaction? How much fault do you want Jessie to have here? Should Jessie have known the consequences of inaction were death, or could he have been oblivious until it was too late? Also, isn't the male spelling "Jesse"?
