Troopers say two people were killed in a crash in Henrietta on Monday morning, and a state trooper was serious injured

HENRIETTA — New York State Police investigators sought to figure out the cause of a near head-on collision on I-390 in Henrietta Monday that killed two people and injured a state trooper.

At about 8:45 a.m., troopers said a Nissan Altima southbound on the interstate crossed the median and was struck broadside by a northbound unmarked Chevy Intrepid police vehicle driven by a New York State Police lieutenant.

“There was nowhere to go to avoid the vehicle coming across in front of her,” declared Major Richard Allen with the state police, “and she took whatever action she could to try to avoid it but just couldn’t avoid it.“

The crash killed the 25-year-old woman driving the Altima as well as a 25-year-old male passenger. The trooper’s vehicle flipped and ended up upside down in the road.

Police said a third vehicle clipped the Altima but the two people in it were not hurt. A passerby helped the trooper out of her upended vehicle, and she was taken to Strong Memorial Hospital. Police described the trooper’s condition as “stable” Monday afternoon.

“She was conscious at the scene,” said Allen.

The northbound lanes of I-390 were closed for most of the day and finally reopened shortly after 3 p.m.

Investigators spent the day examining the scene for clues to the cause of the crash. Police officials described traffic as heavy at the time of the accident and said weather did not appear to be a factor. Overnight rains had stopped, and the roads were dry at the time.

“We have our collision reconstruction unit out there and our Bureau of Criminal Investigations trying to figure out what caused the vehicle to veer off, go across the median,” said Allen.  “Obviously both occupants of the vehicle are deceased, so we are not able to talk to them to try to find out why or what happened."
