Authorities have released the names of the seven people killed Friday in New Hampshire when a truck struck a group of motorcyclists on a two-lane rural highway.

The victims of the catastrophic crash have been identified as members and supporters of the Marine Jarheads Motorcycle Club: Michael Ferazzi, 62, of Contoocook, N.H.; Albert Mazza Jr., 59, of Lee, N.H.; Desma Oakes, 42, of Concord, N.H.; Aaron Perry, 45, of Farmington, N.H.; Daniel Pereira, 58, of Riverside, R.I.; and married couple Jo-Ann and Edward Corr, both 58, of Lakeville, Mass.

The Corrs, who had reportedly been married since July 2, 1983, were just over one week away from celebrating their 36th wedding anniversary together.

The victims were all part of a larger group heading from a hotel to a Jarheads charity event at the American Legion in Gorham, N.H., when they were struck by a 2016 Dodge 2500 traveling in the opposite direction just before 6:30 p.m. Three others who were also injured in the crash were taken to local hospitals for treatment and have since been released, WMUR reports.

The truck's driver, 23-year-old Volodoymyr Zhukovskyy, was arrested Monday morning at his home in West Springfield, Mass., and charged with 7 counts of negligent homicide.

Dr. Beatrice Engstrand, a neurologist who was staying at an inn close to the scene of the crash, rushed to help the injured and later described the chaotic scene to WMUR.

"The truck that hit everybody exploded, so there were flames about 20 feet high and intense smoke in the air," she recalled. "We helped tourniquet the leg so that one guy wouldn't bleed to death."

"It was just terrible," Dr. Engstrand added. "No one thought of taking photos or anything like that. You just want to help the people who were screaming and laying there in the road."

A GoFundMe started by Doug Hayward to benefit the families of the victims has raised $340,250 of its $700,000 goal.

"Our club and the families are going to need help and we cannot do it alone," Hayward wrote. "I am pleading with you all, please do what you can, and 100% of the funds raised will go where it is needed to help ease some of the financial burden left behind after this tragic event. Jarheads MC has always been about helping veterans and their families. We are strong enough to get through this, but we ask for and need your support."
