AUGUSTA (AP) — Maine police have determined the cause of a double fatal motorcycle crash that happened during the United Bikers Toy Run last weekend.

The Kennebec Journal reports the crash occurred on Interstate 95 in Augusta. Police say the chain reaction crash on Sept. 10 started when 25-year-old Aaron White-Sevigny drifted into the passing lane and was struck by a pickup truck driven by 67-year-old William Nusom.

Nusom tried to avoid the motorcycle, struck the median guardrail and hit other motorcyclists participating in the Toy Run.

Fifty-eight-year-old Jamie Gross died at the scene and White-Sevigny died at a hospital.

Nusom and his 99-year-old mother were treated at a hospital.

State police continue to investigate the crash.
