Officials are investigating a deadly crash that claimed the lives of an off-duty Peekskill police officer and a 90 year old Oneonta woman.

Authorities say 29 year old officer Julian Hermosillo was driving on route 17 Sunday night when he apparently lost control of his jeep, crashed through the guardrail and into the path of an Audi sedan. 

Hermosillo and the Oneonta woman, who was riding in the car, were both killed in the crash.
