It will be up to the Georgia Bureau of Investigation to determine the identity of one of two men who died in separate wrecks about 13 hours apart early this week.

Forsyth County Sheriff's Capt. Frank Huggins said the man's body and the 1991 Honda Accord he was driving have been sent to the GBI crime lab after a fiery single-vehicle wreck Tuesday morning on Pendley Road.

A motorist reported the incident about 6:30 a.m. The Accord apparently left the road and struck a tree, Huggins said. It was engulfed in flames when emergency personnel arrived.

Forsyth County Fire Capt. Jason Shivers said it was not clear if the death was caused by the impact or the blaze. Vehicle fires can ignite quickly, especially if a fuel line is ruptured.

Huggins said the second wreck, which happened about 5 p.m. Monday, claimed the life of Roger Lee Adams, 60, of Lakeside Trail.

Adams died at North Fulton Hospital in Roswell of injuries suffered after his 1990 Harley Davidson Ultra Classic collided with a sport utility vehicle on Bald Ridge Road at Lanier 400 Parkway.

The intersection is near Exit 15 at Ga. 400.

Huggins said it appears 21-year-old Diego Castaneda of Canton pulled a 2001 GMC Yukon into the path. The motorcycle struck the driver’s side door of the Yukon.

Adams was wearing a helmet, though Huggins said it was not a type approved by the state Department of Transportation.

He said Castaneda likely will be charged in connection with the wreck.
