Salvador Tapia carried a semiautomatic pistol, an extra clip of bullets and a cryptic note when he stormed into a South Side auto parts shop about 8:30 a.m. Wednesday.
The note, in Spanish, seemed to threaten his girlfriends, according to the Chicago Sun-Times.
Tapia–“a bomb waiting to explode,” as a girlfriend described him–chased, cornered and executed six of his former co-workers and exchanged gunfire with police in a gritty Canaryville industrial neighborhood before being killed by sharpshooting cops.
The scruffy, tattooed, 36-year-old Tapia had a mean streak. He pointed weapons at family members, beat girlfriends and threatened his boss. His friends say he had a short fuse. At work, he was often late, argumentative and eventually fired. Wednesday, he was furious about that firing six months ago from his job of shelving used engine parts at Windy City Core Supply Co.
