John

This man was employed by Sophia Leigh and shoots people for her. He also claims that his father and grandfather worked for her.

He shoots at Lara Croft when she is travelling the rooftops of London. Lara repells him and brings him down then questions him. Lara doesn't quite believe that the hitman's father and grandfather could have worked for Sophia if she is only in her late twenties or early thirties. The hitman takes a chance to grab his gun and succeeds. But before he can kill Lara he is hit from behind by the swinging bell. He goes flying across the rooftops and presumably dies.
