Vladimir Zhukovsky has been charged with seven negligent homicide charges that he was under the influence of one or more drugs in the crash, seven other negligent homicide charges, seven murder charges, one drunk driving charge and one drunk driving charge. for reckless behavior, guidance.
He had previously pleaded guilty to seven counts of negligent homicide. CNN was unable to contact a lawyer for Zhukovsky.
Zhukovsky was driving erratically and crossed the double-yellow centerline before reaching the group of motorcyclists on June 21, investigators said.
Seven motorcyclists were killed and three others were injured in Randolph, New Hampshire in the crash.
Zhukovsky is scheduled for video consent and a bail hearing on the new charges on November 5.
His license was already due to be suspended
A month before the crash, Zhukovsky was arrested on charges of operating a motor vehicle under the influence of drugs and / or alcohol, a police report shows.
A witness told police that the truck driver had knocked over the truck's engine and jumped outside the vehicle on May 1
But miscommunication between Massachusetts and Connecticut led Zhukovsky to retain his driver's license, said Stephanie Pollack, secretary and executive director of the department.
In a statement, Pollack placed part of the blame on Connecticut, saying that the state Department of Motor Vehicles waited 18 days and used a state-by-state special messaging system to alert Massachusetts of the driver's charges.
And that message, according to the department, does not contain enough information to automatically add charges from May 11 to Zhukovsky in Massachusetts.
"To the knowledge of [Registry of Motor Vehicles’] Connecticut failed to provide sufficient information" through the federal system, which states use to share information about violations, the Massachusetts DOT said.
CNN previously contacted DMV for Connecticut for comment.
