Burglar 1 (Sleeper)

A burglar and his accomplice robbed the house of Keryehla Janees and Mike Lyndon. His accomplice was slaughtered by Keryehla, who was actually a member of an alien sleeper cell. Terrified, he jumped out of the window to escape her and landed on a parked car below. Though he survived, he was badly injured and taken to the Cardiff Royal Infirmary where he soon died. Jack Harkness and Gwen Cooper heard him trying to get away from Keryehla Janees, making it clear she was the murderer. (TV: Sleeper)
