CONCORD, N.H. — The driver of a truck in a collision that killed seven motorcyclists was charged Monday with seven counts of negligent homicide, authorities said.

Volodoymyr Zhukovskyy, 23, was arrested Monday morning at his home in West Springfield, Massachusetts, on a fugitive from justice charge related to Friday’s crash, the New Hampshire attorney general’s office said.

He was expected to make a court appearance on the charge Monday afternoon in Springfield.

A man who answered the phone at the home of Zhukovskyy’s family and would identify himself only as his brother-in-law said Monday that the family is in shock and feeling the same pain as everyone else but couldn’t say whether the driver was right or wrong.

Zhukovskyy’s pickup truck towing a flatbed trailer collided with a group of 10 motorcycles Friday on a two-lane highway in the northern New Hampshire community of Randolph, investigators said.

The victims were members or supporters of the Marine JarHeads, a New England motorcycle club that includes Marines and their spouses, and ranged in age from 42 to 62.

The circumstances of the wreck have been mysterious.

The uncle of one of the victims said Sunday that he was trying to comprehend how so many bikers died in one accident.

“The truck was coming in the opposite direction. It’s hard to figure how he could hit 10 motorcycles without getting out of the way,” Joseph Mazza said. “Right now, the details are very vague. I’m very confused ... I need more information.”

Authorities identified the dead as Michael Ferazzi, 62, of Contoocook, New Hampshire; Albert Mazza Jr., 59, of Lee, New Hampshire; Desma Oakes, 42, of Concord, New Hampshire; Aaron Perry, 45, of Farmington, New Hampshire; Daniel Pereira, 58, of Riverside, Rhode Island; and Jo-Ann and Edward Corr, both 58, of Lakeville, Massachusetts.
