Nebraska ? A teenager who lived with the suicidal gunman who fatally shot eight people in a mall told police afterward that he had seen writings in which the suspect described killing himself in public, according to a court document filed Friday.

Kraig Kovac, 17, told police that the writings by Robert Hawkins scared him and that he had talked to his mother about them, according to a search warrant affidavit filed in Douglas County Court. He also told police that his family was “making a decision to kick him (Hawkins) out,” the document says.

Kraig Kovac’s mother, Debora Maruca-Kovac, said Friday that she doesn’t agree with that account because the first she knew that Hawkins was thinking of killing himself was when she read suicide notes he had left.

The suicide notes hinted at his plans but did not specifically describe committing suicide in a place with many people. The affidavit did not state exactly when Kraig Kovac read Hawkins’ writings about public suicide, saying only that it was “recently.”
