BEAR, Del. (AP) -- State police are investigating a motorcycle accident that left a Delaware man dead.
Authorities say 49-year-old Thomas J. Miller died after the accident shortly before 6 p.m. Saturday.
Investigators say Miller was operating a 2001 Harley Davidson Electra Glide motorcycle on Howell School Road at Robert C. Peoples Boulevard when he failed to negotiate a new roundabout circle that opened to traffic a few months ago.
Authorities say the motorcycle struck a raised concrete curb and fell on its side, ejecting Miller.
Miller was not wearing a helmet. He was pronounced dead at a hospital about two and a half hours later.
