Police say the gunman who barricaded the doors of a Pennsylvania grocery store and shot three coworkers before killing himself detailed his horrific plan online in the weeks and months before the murders. The New York Daily News reports Randy Stair, 24, brought two shotguns concealed in a duffel bag to his night shift at Weis Market in Tunkhannock on Wednesday. Around 1am Thursday, he blocked the entrances and exits then fired 59 shots, killing Victoria Brong, 26; Brian Hayes, 47; and Terry Sterling, 63. An unidentified witness was able to flee the scene and call 911. The Press & Sun-Bulletin reports that Stair's online postings indicate that he could have been planning the killing spree for up to four months. A 37-minute video posted on May 11 on one account allegedly lays out Stair’s plan of attack.
“What’s going to happen in the future after this to prevent this from happening again?” he asks at the end of the recording, where he displays weapons and names employees scheduled to work on June 7. "And the answer is you can’t prevent it. You can only endure it." A long trail of social media accounts believed to be run by Stair under the pseudonym Andrew Blaze, a female cartoon character Stair said represented himself, contain more chilling clues, including an Instagram post of Stair at work the night of the shooting and a final tweet posted at 9pm Wednesday that read: “Goodbye humans...I'll miss you....” Stair also referenced the Columbine shootings in a YouTube video posted Wednesday that he dedicated to killers Dylan Klebold and Eric Harris.
