Oct. 18--A Nassau County highway patrol officer has been struck and killed while investigating an accident early Thursday on the Long Island Expressway, according to Nassau County and police sources.
The officer, who had been on the force since 1998, was fatally struck about 5 a.m. Thursday in North Hills. The officer was out of his car to investigate an accident in the HOV lane when he was struck and killed by a vehicle, according to Nassau County officials with knowledge of the investigation.
The two-vehicle accident closed all eastbound lanes of the Long Island Expressway in North Hills early Thursday, according to the state Department of Transportation, backing up traffic to Queens.
Informny.com, the department's website, reported a two-vehicle accident at 4:46 a.m. between Exits 34 and 36.
A Nassau County police traffic advisory sent via email at 5:20 a.m. said eastbound lanes of the expressway were closed at Exit 35.
Nassau County Police Commissioner Thomas Dale and County Executive Edward Mangano announced they would hold a noon news conference about the accident.
Nassau Police Officer Michael Califano, 44, of Wantagh, was the last Nassau County police officer killed in the line of duty during a traffic stop. He died after a flatbed truck struck his patrol car Feb. 4, 2011, on the Long Island Expressway.
