Mall shooter's best friend arrested

BELLEVUE, Neb., Dec. 7 (UPI) -- Bellevue, Neb., police arrested a friend of the man who killed eight people at a mall after the man allegedly threatened someone who spoke ill of the shooter.

David Horvath, 17, allegedly threatened Shelby Harrington, for posting uncomplimentary statements about Horvath's best friend, Robert Hawkins, on the Internet, Shelby's father, Kevin Harrington said, the Omaha (Neb.) World-Herald reported Friday.

Hawkins, 19, killed eight people and himself Wednesday at Westroads Mall.

"(Horvath) said, 'If you say anything else bad about Robbie, I will put a cap in your head,'" Harrington said.

Shelby Harrington, 16, recorded the threat on her cell phone, the World-Herald said.

She said Hawkins had threatened to kill her two weeks ago.

"He said 'I'm going to kill you, I am going to kill your family and I'm going to burn your house down,'" Shelby Harrington said.

Horvath was arrested on suspicion of making terroristic threats.
