An avid bicyclist was found with a serious head injury on a Dix Hills roadway Wednesday afternoon, said Suffolk police as they asked for the public's help to determine what happened.
A passing motorist spotted Paul Rovelli, 69, Deer Park, lying next to his bike about 1:20 p.m. on the southbound roadway of Carlls Straight Path near Villadom Court, police said.
Rovelli, who was wearing a helmet, was semiconscious and taken to Huntington Hospital, where he was listed in serious condition Wednesday night, said Det. Sgt. John O'Sullivan of the Second Precinct.
Because of his head injury, Rovelli was unable to tell detectives how he was hurt, and police are looking for anyone who may witnessed something or seen the bicyclist shortly before he was injured.
O'Sullivan said there was no indication that a vehicle was involved and no surveillance footage nearby because one side of the road is bordered by woods and the other by a curb with bushes. The two houses closest to where Rovelli was found don't have a view of the roadway there, he said.
Detectives are trying to determine if Rovelli had a medical episode.
"A 69-year-old avid bicyclist -- it's great that he's out there and unfortunate that something like this happens," O'Sullivan said. "We're hoping . . . somebody might say they saw him somewhere or before this or who knows."
Rovelli had on black, nylon bicycle pants, a yellow helmet and a gray windbreaker, police said. His bike is a sports model often ridden by professional bicyclists, police said.
