The investigation is ongoing, Olsen said, but evidence gathered so far shows the tour bus was traveling “at a high rate of speed” when it struck multiple vehicles driving slow through a work zone. The result was “a chain reaction crash” involving at least eight vehicles.
Dong was arrested on Saturday by the Virginia State Police and served with felony warrants in the hospital, Olsen said.
Each count of involuntary manslaughter carries a maximum penalty of 10 years in prison.
Five people died in the accident, including a 44-year-old female, a 13-year-old female, and a seven-year-old male. They were in a car that caught fire and had been on their way to a wedding in South Carolina, according to CBS, the BBC’s US news partner.
They were identified to CBS News Boston as a family from Greenfield, Massachusetts – Dmitri Doncev, his wife, Ecaterina, their daughter Emily and son Mark.
The fifth victim, 25-year-old Priscilla Mafalda, was in the Suburban that was initially struck by the bus.
The bus was operated by E&P Travel and heading to North Carolina from New York.
Roughly 44 people were sent to area hospitals after the collision, three with critical injuries, police said.
