UPDATE: 80-Year-Old Admitted to Stony Brook with Serious Injuries, Police Say

Update, Tuesday, 11:45 a.m.: John Glennon, an 80-year-old passenger involved in Monday afternoon's accident in Amagansett has been admitted to the hospital with serious injuries, according to East Hampton Town police.

Glennon is listed in critical condition, according to Stony Brook University Medical Center. He was flown to the hospital in a Medevac helicopter after the accident, which was reported to police at 4:03 p.m.

Detective Lt. Chris Anderson said a 2012 Chevrolet Avalanche, driven west by Eleanor Glennon, 81, struck a commercial truck, parked on the westbound side of Cranberry Hole Road. Anderson said the truck — a 2004 GMC — was unoccupied and left partially in the roadway.

Eleanor Glennon and two children, 6 and 7 years old, were transported to Southampton Hospital with minor injuries, and released, police said.

"We're exploring the possibility that sun glare played a role," Anderson said.

While no violations of the Vehicle and Traffic Law were issued, Anderson said that the truck's owner was sited. The Suffolk County Police Department's Highway Patrol Unit issued 16 violations of the Code of Federal Regulations to DJ Whelan Corp., all having to do with equipment on the truck.

The county police unit was called to inspect the vehicle at the scene of the accident, Anderson said. The unit handles inspections of commercial vehicles.

The truck cannot be used until the CFR violations are corrected, he said.

Three ambulances were called to the scene of the accident, including one from the Montauk Fire Department, which arrived just before 4:30 p.m.

One patient was taken by ambulance to the helicopter landing zone to be transported to Stony Brook University Medical Center. At least one other patient was transported to Southampton Hospital.

Cranberry Hole Road is closed, though it could not be immediately confirmed between which roads.

East Hampton Town police are on scene. Chief Ed Ecker, who was not on scene, said he believed the accident involved one car, with four occupants, that hit a parked truck.
