(CBS/AP) PHILADELPHIA - Ronald Wagenhoffer, 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 Thursday.
Wagenhoffer, 52, was found dead Wednesday night in a pickup truck with a self-inflicted gunshot wound to the chest, according to Philadelphia police. Deputy Mayor Everett Gillison said Wagenhoffer was a Department of Licenses and Inspections employee who had inspected the building May 14.
Department employees were being informed of the death Thursday morning.
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. His attorney has said he was being made a scapegoat.
The city's top prosecutor has convened a grand jury to investigate whether anyone else should face criminal charges.
A demolition permit indicates that contractor Griffin Campbell was being paid $10,000 for the job. Campbell's lawyer has called him despondent but "absolutely not responsible" for the deaths. On Thursday, he released a statement expressing condolences to the inspector and the families.
"Our heartfelt condolences go to the family of the inspector," attorney Kenneth Edelin said in a statement. "We also continue to pray for the families of those that were lost, and for the health and speedy recovery of those that were injured."
Wagenhoffer is described as a dedicated 16-year veteran of the Department of Licenses and Inspections. Deputy Mayor Gillison says the department is in mourning and Wagenhoffer "did nothing wrong." Wagenhoffer leaves behind a wife and son.
