Andrew J. Engeldinger's descent into darkness began two years ago, but even as he retreated from family and bought handguns and ammunition, he kept coming to work at the Accent Signage Systems factory in Minneapolis.
Engeldinger, 36, worked his shift Thursday and was told that after a dozen years, he no longer had a job. Then he pulled out a 9mm Glock handgun and committed the largest workplace massacre in recent Minnesota history.
On Friday, the scale of the rampage came into focus: Five people were killed, including the founder of the acclaimed sign manufacturer and a visiting UPS driver. Three others were injured.
Police Chief Tim Dolan said Engeldinger apparently spared some employees in "the hellish time" as workers dialed 911 and hid in terror. It all ended in minutes, after Engeldinger went into the building's basement and fired a final bullet into his own head.
Police who searched his home across town in south Minneapolis found a second handgun and packaging for 10,000 rounds of ammunition, but no obvious answers.
"Maybe something finally snapped, but I don't know why," said his uncle Joseph Engeldinger.
The victims included company owner Reuven Rahamim, 61, of St. Louis Park; United Parcel Service driver Keith Basinski, 50, of Spring Lake Park; Rami Cooks, 62, of Minnetonka; Ronald Edberg, 58, of Brooklyn Center and Jacob Beneke, 34, of Maple Grove.
Two employees remained hospitalized at Hennepin County Medical Center late Friday afternoon. Accent's director of operations, John Souter of Wayzata, was in serious condition and production manager Eric Rivers was in critical condition.
