RALEIGH — Police are hoping an autopsy report will help them determine why a Chatham County man was going 90 mph Friday morning when his Ford sport utility vehicle left Interstate 40 and slammed down onto Gorman Street on the south side of Raleigh.
William Darryl Martin, 52, was the SUVs only occupant and was declared dead at the scene of the accident. Martin, who lived in Siler City, was a supervisor for the Orange County Water and Sewer Authority.
Raleigh police have completed their scene-related portion of the investigation, but they are still searching for answers, said police spokesman Jim Sughrue.
If anyone can provide additional information, please call, Sughrue said Monday.
Sughrue said investigators are awaiting the results of an autopsy to help them figure out the underlying cause of the accident. He said its not clear if Martin had a medical condition that may have contributed to his speed or his drifting off the road.
Anything said at this point would be speculative, he said.
According to an accident report made public Monday, Martin was driving an OWASA SUV east on I-40 just after 10 a.m. when he ran off the left side of the road into the median. Investigators said the SUV traveled at least 800 feet in the median before reaching the Gorman Street underpass, where the SUV went airborne and fell about 30 feet onto the street, according to the accident report.
Martin, who went by Dusty, was operations supervisor at OWASAs Jones Ferry Road Water Treatment Plant. He had previously worked at treatment plants in Lee County, Cary, Siler City and Chatham County before joining OWASA in 2007.
He is survived by a wife and two sons.
