In the weeks after Minnesota's worst workplace shooting in recent history, investigators scoured Andrew Engeldinger's laptop, digital camera and telephone for any clues to explain why he killed six people before shooting himself in the head.
They came up empty.
Forensic experts from the Minneapolis Police Department examined 38,942 images and more than 200 videos and noted that none of them was of "immediate, recognizable, relevance," according to crime scene and personnel documents obtained by the Star Tribune on Monday. What they did find was 6,373 hits on the word "Glock," and files created in October 2011 related to buying the gun and applying for a federal firearms license.
Engeldinger, 36, shot his victims with a Glock 9-mm semi-automatic pistol at Accent Signage Systems in Minneapolis after he was fired from his job. A manila envelope marked "Andy" with his final paycheck of $968.46 was found on the office floor of Director of Operations John Souter, one of a pair of employees who were shot and survived.
There was a letter in Engeldinger's personnel file dated the week before the shootings from his supervisor, Rami Cooks, warning him about his chronic tardiness and saying that "we need to rectify this issue immediately."
"We have discussed your chronic late arrivals several times in person, but the message does not seem to be getting through," Cooks wrote.
A gruesome scene
The 20-page forensic report detailed what officers saw when they reached Accent in the late afternoon of September 27. In addition to Minneapolis SWAT teams, a slew of Brooklyn Park police officers gathered outside the building in case a "secondary mission" was necessary. An armored vehicle also was brought to the scene, as well as a bomb squad to handle a gray backpack found inside a loading door and to search Engel- dinger's car.
