And if so, what was the outcome? I think this would be one of the best ways for a real sicko with a grudge against someone to really extract revenge.
For those unfamiliar or have forgotten- woman marries a series of guys, all are murdered, only thing in common is this woman. But it turns out, her sister was killing the men b/c she didn’t want her sister to be married. I think.
Or, in my scenario, say you don’t like Bob, so you kill his aunt, mechanic, 5th grade teacher, secretary and pizza delivery boy. A good detective will make the connection, and with no other connection, they have a decent case on circumstantial evidence, especially if it turns out he was porking the secretary, had a dispute with the mechanic, failed the 5th grade, received the wrong pizza, etc.
