(NEWSER) – The man who inspected a Philadelphia building three weeks before it collapsed last week, killing six and injuring 13, has died in an apparent suicide. The 52-year-old, whose name has not been released, inspected the building several times and ruled it safe after a complaint was lodged last month, reports NBC. He apparently shot himself in the chest while parked in his pickup truck in an isolated area about a mile from his home, where his wife found him. His suicide note had been a text to her. Meanwhile, a crane operator awaits trial in the collapse, while victims are suing the demolition contractor.
