A former NYPD auxiliary deputy inspector who served as a first responder on September 11, 2001, was killed in a car crash in the Catskills on Monday. His wife and future son-in-law also perished in the crash.

Morris Faitelewicz, 58, was killed at around 4:30 p.m. yesterday after his SUV rolled over on Route 17 in Sullivan County, New York. His wife, Beth Faitelewicz, and Yehuda Bayme, who was engaged to his daughter, was killed as well—daughter Shani and sons Yaakov and Avi survived, but were injured. The cause of the crash remains under investigation.

Both Morris and Beth Faitelewicz, who lived on the Lower East Side, helped with 9/11 recovery operations, Morris Faitelewicz as a first responder, and Beth Faitelewicz as a nurse at Beth Israel. "She always told the story how she and her coworkers waited for survivors, victims to come in wounded from 9/11, and nobody ever came. That's when they realized there were no survivors," Betty Goodman, a family friend, told NBC News. Morris Faitelewicz was once honored for his efforts by ex-Assembly Speaker Sheldon Silver.

“Beth and Morris didn’t just lend a hand to help downtown recover from 9/11,” former Michael Bloomberg spokesman Stu Loeser said in a statement yesterday. “They put everything they had into helping Lower Manhattan and the City come back.”

The surviving passengers are all in serious but stable condition at a local hospital.
