KAMLOOPS, B.C. -- A judge in Kamloops, B.C., has ordered a psychiatric assessment for a man accused of killing his girlfriend in Alberta, slashing an undercover police officer in B.C. and stabbing a fellow inmate in the eye during a game of Scrabble.

The order for Mark Lindsay came one day after Lindsay told the court he killed 31-year-old Dana Turner last year because he believed she was a serial killer and his life was in danger.

Lindsay also admitted to attacking the undercover officer last year and stabbing an inmate in a Kamloops jail after his arrest for the assault on the officer.

He testified a group of serial killers was after him over false allegations that he sexually assaulted one of their friends.

Lindsay said Turner was one of the killers and he killed her in a panic before dumping her body, which was found last October in a field near Innisfail, Alta.

Lindsay, the son of former Edmonton Police chief John Lindsay, is charged with second-degree murder in Turner's death.
