PHILADELPHIA: An inspector who surveyed a downtown building weeks before it collapsed, killing 6 people, was found dead from a self-inflicted gunshot wound a week after the accident, authorities said yesterday.

The 52-year-old man’s body was found Wednesday night in a pickup truck with a self-inflicted gunshot wound to the chest, according to Philadelphia police. Deputy Mayor Everett Gillison said the man was a Department of Licenses and Inspections employee who had inspected the building May 14.

Investigators say a heavy equipment operator with a lengthy rap sheet was high on marijuana when a building under demolition collapsed onto a neighboring thrift store on June 5.

The operator, Sean Benschop, faces six counts of involuntary manslaughter, 13 counts of recklessly endangering another person and one count of risking a catastrophe.
