Authorities say a New York father is facing involuntary manslaughter charges after his daughter flipped his SUV, killing three teens.

Prosecutors say Michael Ware let his underage, unlicensed daughter drive his SUV. Authorities say the 15-year-old girl was tearing down a road in the Poconos over Labor Day weekend when the vehicle flipped, killing three teen boys. The driver and two other teens survived.

According to investigators, passengers pleaded for the teen to slow down, but she ignored them.

Investigators say this was not the first time that Ware allowed his daughter to drive the SUV, and they say he allowed her to drive to the Poconos on the day before the crash.

Ware’s lawyers say that he didn’t give his daughter permission to drive the car on the actual day of the crash.
