Employee who killed six in shooting spree was ‘angry at the world’

THE car-parts warehouse, with only one entrance, was a maze of crates and 55-gallon drums.

So when former employee Salvador Tapia walked in and started shooting, police said he had effectively cornered all seven people inside.

After fatally shooting six, including two brothers who owned Windy City Core Supply, Tapia went outside and opened fire on police.
