The identity of the 25-year-old Massachusetts motorcyclist who died late Thursday in a collision on Black Rock Turnpike was released Monday by police.

Nathan Stebbins of Ludlowe, Mass., died from injuries after colliding with a BMW near the intersection of Black Rock Turnpike and Congress Street, not far from the Merritt Parkway.

Stebbins, who police said was not wearing a helmet, apparently tried to "drop his bike" about 30 yards before the collision, said Lt. Jim Perez, a Fairfield police spokesman, in an attempt to avoid being struck.

No charges were filed in the immediate aftermath of the crash, but am investigation of the incident is continuing.

The BMW driver, a 53-year-old Fairfield woman, told police that she was traveling north on Black Rock Turnpike, and that the motorcycle was headed east on Congress Street.

Perez, however, said Friday that a preliminary investigation by an accident reconstruction team could indicate the motorcycle was traveling south on Black Rock Turnpike. "I think she was confused," said Perez, who added the BMW driver was on her way home from the Patterson Club on Cross Highway.

Perez said weather at the time of the 11 p.m. Thursday crash did not appear to be a factor.

An employee of a security company was the first to stop at the accident scene, and was joined shortly by Officer Scott Sudora. Both men tried to render medical aid to the injured Stebbins until an AMR Ambulance arrived at the scene, according to police. He was taken to St. Vincent's Medical Center in Bridgeport, where he later was declared dead.

Trumbull police sent accident reconstruction officers and equipment to help investigate the crash.

"Tragically, we had two victims last night, one who succumbed to his injuries and one who was shocked at what transpired in an accident like this," Perez said. "When life is lost, no one wins and we feel for both families."
