Spokesman for the Alaska Department of Corrections says John Carlin, the gunman in a notorious Alaska killing, has been found dead at the state prison in Seward.Corrections spokesman Richard Schmitz says Carlin was found dead under suspicious circumstances Monday night.Carlin was convicted of conspiring with Mechele Linehan, a former Anchorage stripper turned soccer mom, in the 1996 shooting death of Linehan's fiance, Kent Leppink. Leppink's body was found off a trail south of Anchorage.Prosecutors say Linehan and Carlin orchestrated the killing in the mistaken belief that Linehan would receive insurance money. Carlin was sentenced in January to 99 years in prison for firing the shots that killed Leppink.Prosecutors claimed Linehan tried to follow the plot of "The Last Seduction," a1994 movie in which a woman gets her lover to kill her husband.Leppink, a commercial fisherman, was shot to death with a handgun at close range on a trail outside the tiny mining community of Hope, Alaska.Linehan was arrested 10 years later in Washington, where she lived a quiet life married to an Olympia doctor.
