What was Al most famous killing?

Please provide more context. Who is "Al"? There are many famous people with names starting with "Al," and it's impossible to guess who you're referring to without more information.

For example:

* Al Capone was a famous gangster, but his killings weren't particularly famous.

* Al Pacino is an actor, and while he plays characters that commit murders, he doesn't commit them in real life.

* Al Gore is a politician, and there's no record of him killing anyone.

Please give me more details about the "Al" you're asking about so I can give you a proper answer.
