Top British murderer commits suicide
LONDON -- The once-respected family doctor who became Britain's worst serial killer was found hanged in his prison cell Tuesday, cheating his victims' relatives of the one consolation they had hoped for -- an explanation of his 23-year murder spree. Officials are investigating why there was no suicide watch on Dr. Harold Shipman, who was convicted in 2000 of killing 15 patients and later was found to have murdered at least 200 more, mostly by lethal injection. He always maintained his innocence.
