A Raleigh man trying to steal a catalytic converter from a disabled car was killed when the jack he used to get under the vehicle failed and pinned him underneath, the Wake County Sheriff’s Office said in a press release yesterday. Deputies responding to a call on Monday morning found the body of a man under a car. The body was discovered by a tow truck driver who had been dispatched to that location to tow the disabled Toyota Camry, the sheriff’s office said.
