A 15-year-old girl and her 39-year-old mom were killed Wednesday in a car crash on Route 101 in Exeter, New Hampshire, state police said.

The crash was reported at 8:40 p.m. after a vehicle traveling westbound crashed near the area of Exit 9. New Hampshire state police were informed that a 2000 Volkswagen Jetta lost control and veered off the road, resulting in a rollover crash.

Manchester, New Hampshire resident Rebecca Lafontaine, 39, was pronounced dead at the scene. Her daughter, Julissa Clem, 15, sustained life-threatening injuries and was taken to Exeter Hospital, where she died.

The driver of the vehicle, who was identified as 28-year-old Aaron Lafontaine from Manchester, New Hampshire, was taken to Portsmouth Regional Hospital with life-threatening injuries. He was then airlifted to Massachusetts General Hospital in Boston.

Brandon Vallone, Lafontaine's cousin, says Lafontaine swerved to avoid a deer, overcorrected and rolled the car. He says the family of three were on the way home from Hampton Beach.

Vallone also said that Lafontaine remains in critical condition. According to Vallone, he has a broken sternum, collapsed lung, broken ribs and brain swelling.

A preliminary investigation suggests speed may have been a factor in the crash. However, officials are continuing their investigation to determine the cause, according to state police.
