KNOXVILLE, Tenn. (WVLT) -- The cable worker who died on the job Monday night was thrown from the bucket he was in when a passing truck's rear bumper snagged a steel cable laying on the ground, according to a new report from the Knox Co. Sheriff's Office

According to the Motor Vehicle Accident report, released Wednesday morning, Bruce Lee Marion was working in a bucket lift 18 feet above Beaver Creek Lane near the Central Avenue Pike interchange. While working on a cable that stretched across Central Avenue Pike dropped off the pole.

The 29 year-old was still holding onto the cable when a passing GMC* pickup truck drove over the cable. Its rear bumper caught cable, stretching it before finally breaking free. The taut cable caught Marion, throwing him to the ground.

Two witnesses told police Marion may have pulled the cable while he was still driving over it.

Marion was working for H&R Cable at the time.

The Sheriff's Office said the driver of the pickup will not be charged. OSHA, or the Occupational Safety and Health Administration, has taken over the investigation.

* - An earlier version of this story based on police reports identified the truck as a Chevrolet.
