Do you know anyone who was murdered? My stepdaughter's best friend was.

Unfortunately I do, in 1980 my step brother was murdered by serial killer William G Bonin, he was also known as the freeway killer in Los Angeles.

My cousin's son murdered in a drive-by a few years ago. I wasn't close to him so there's that.

A friend was murdered for the $4000 cash she was in possession of.

Maybe.

When I was in elementary school, there were twin girls who didn't return after summer vacation.
We were told they died in a house fire.
I later found out the fire was "suspicious" according to fire fighters - but there wasn't enough evidence to rule it arson.
