PHILADELPHIA — A 42-year-old man who was allegedly high on marijuana while operating demolition equipment when a downtown building collapsed and killed six people will be charged with involuntary manslaughter, a top city official said Friday.
Sean Benschop faces six counts on that charge, six counts of risking catastrophe, and other charges, said Deputy Mayor Everett Gillison.
Authorities said Benschop was using an excavator on Wednesday when what was left of the four-story building fell on a neighboring Salvation Army thrift store.
A toxicology report, witness statements, and other evidence showed that Benschop was high on marijuana that day, Gillison said.
Benschop, who also goes by the name Kary Roberts, has been arrested at least 11 times since 1994 on charges ranging from drugs to theft to weapons possession, according to court records. He was twice sentenced to prison in the 1990s after being convicted on drug trafficking charges.
Benschop’s last arrest, for aggravated assault, came in January 2012, but the case was dismissed for lack of evidence.
Police have raided Benschop’s home but have not found him, Gillison added.
Benschop did not return phone messages left at numbers listed in his name, though he told The Philadelphia Inquirer on Thursday that he couldn’t comment because of the investigation.
Among those killed was a woman who was working her first day at the store. Thirteen people were hurt.
Video shot of the scene shortly before the fatal collapse show bricks falling onto a sidewalk, which remained open to pedestrians, as a worker used heavy equipment to take out a front wall.
