HistoryTen years before the start of Season Four his wife is killed by Lloyd Paulsen. At some unknown point after his wife's death, he got hit by the bus and remained in a persistent vegetative state. He had to stay in the hospital for several years since then.
The killer was never caught until the police began a DNA sweep to find the Trinity Killer. Lloyd Paulsen gave his DNA at a checkpoint and as a result he was arrested on DNA evidence found at the crime scene. Later Angel and Maria visited him at hospital. Angel told him that his wife's killer was finally caught and apologized to him for not catching the killer sooner.
