– By David Chang and Vince Lattanzio (NBC 10) –

The lead inspector of a Center City building that collapsed last week is dead after he committed suicide, according to multiple law enforcement sources close to the investigation who did not want to be named.

Law enforcement sources say the man shot himself once in the chest and was found dead inside his truck along the 100 block of Shawmont Avenue in Philadelphia around 9:30 p.m., less than a mile from his home. The man didn’t leave behind a note but did text his wife before pulling the trigger, according to sources.

The sources also tell NBC10 that the victim inspected the building on 2136 Market Street several times prior to last week’s accident. According to the sources, the victim said the site was safe after the city received a complaint about the project back in May.

NBC10.com is withholding his name until his family is notified.

Last Wednesday, the four-story outer wall of the building crumbled onto the Salvation Army Thrift Store next door. Six people were killed in the collapse — three employees and three patrons. The wall also buried 13 others throughout the store – including in the basement. They were eventually rescued by citizens and first responders.

Excavator operator Kane R. Robert, also known as Sean Benschop, stands charged in the collapse and now a grand jury is being convened to uncover whether other people should be held responsible.

The city was quick to change regulations for demolition contractors after the collapse.
