PHILADELPHIA (CBS) — Sources tell CBS 3 that blood tests on the crane operator involved with Wednesday’s deadly building collapse in Center City detected the presence of a prescription painkiller and marijuana.
The blood, along with urine, was taken from 42-year-old Sean Benschop at the hospital approximately two hours after the collapse at 22nd and Market Streets, which killed six people and injured 13.
