Two teen brothers remained hospitalized Wednesday for treatment of serious injuries they sustained when the minivan they were riding in was hit by another vehicle at a Commack intersection, police said. The Tuesday accident was caused by the effects of superstorm Sandy because the stoplights weren't working, Suffolk police said.

The two passengers, Tyler Smith, 18, and Sean Smith, 19, were taken to Southside Hospital in Bay Shore and admitted in serious condition after the 5:10 p.m. Tuesday accident at Motor Parkway and Moreland Road, police said.

Police said the injured brothers were passengers in a 1994 Plymouth Voyager driven by Jenna Concolino, 18, of Centereach. She was northbound on Moreland Road when her vehicle was struck by a 1983 Cadillac westbound on Motor Parkway.

The Voyager then hit a 2003 Jeep driven by Michael Henry, 27, of Commack, who was southbound on Moreland Road and trying to turn onto Motor Parkway.

The three drivers had minor injuries in the accidents. Concolino, Henry and the Cadillac driver, Daniel Kleeman, 18, of Commack, were treated at hospitals and released.

Fourth Squad detectives are investigating the crash, in which the intersection's traffic lights were inoperable due to a loss of power caused by the storm, police said.
