AUGUSTA — A Whitefield crash that killed a 16-year-old driving an all-terrain vehicle last June has led to a lawsuit against the mother of the girl driving the car that collided with the ATV.

The civil lawsuit was filed recently in Kennebec County Superior Court by Stacy Savage, of Oakland, as personal representative of the estate of Ryan Wayne Mullens, and names Karen Crommett, mother of Kimberly Crommett, of South China, as the defendant.

Mullens, of Whitefield, died June 23, 2014, after his ATV crashed into a vehicle driven by Kimberly Crommett, 16.

The crash was reported around 7 p.m. as both teens drove north on Howe Road in Whitefield, according to a news release from the Lincoln County Sheriff’s Office that was issued after the incident.

Mullens, driving a Yamaha ATV, was following Crommett, who was driving a Subaru station wagon.

“The ATV entered the southbound travel lane to overtake the Subaru,” police said in the release. “As the ATV returned to the northbound lane it crossed the Subaru’s path and both collided on the side of the roadway.”

The ATV rolled over, throwing Mullens, who was not wearing a helmet. The Subaru stopped on the side of the road.

Emergency responders took Mullens to MaineGeneral Medical Center in Augusta, where he later died.

Investigators never provided the name of the girl driving the Subaru, but she was named in the lawsuit filed by Savage’s attorney, Jason Jabar. The lawsuit says Kimberly Crommett was negligent in operating the car, “causing Ryan Mullens to crash his all-terrain vehicle,” and seeks unspecified compensation for damages.

“It was obviously a very sad, tragic accident,” Jabar said recently.

Jabar said the teens knew one another.

He said he anticipated the lawsuit would be defended by an attorney for the insurance company that provided coverage for the vehicle.

On Tuesday, attorney Jessica Adler Coro responded on behalf of Karen Crommett, denying the claims of negligence and asking for dismissal of the complaint. The defense also says, among other things, that the plaintiff’s right to recover damages “will be reduced or eliminated to the extent the plaintiff may be found to have comparative fault.”

Attorney John Schulte, who works with Coro, said the firm does not comment publicly on litigation. A phone number listed for the Crommets in South China is no longer working.
