Police have released the identities of two people who were killed in a collision between a pickup truck and the motorcycles they were riding.

WABI-TV reports 58-year-old Jamie Gross of Belmont and 25-year-old Aaron White-Sevigny of Windsor were the motorcyclists who died as a result of the crash. Two other bikers, 50-year-old Trevor Proctor and 46-year-old Tori McGraw were both taken to the hospital with road rash. The driver of the pickup, 67-year-old William Nuson, and his 99-year-old mother Anna suffered minor injuries when their vehicle overturned.

Hundreds of motorcyclists were taking part in the Annual United Bikers Toy Run and had just left the Augusta Civic Center when the accident happened shortly after noon on Sunday. The bikes were in the right-hand lane of the interstate, with other traffic traveling in the passing lane. Police are now working to determine exactly how the pickup and motorcycle collided.
