GREENFIELD — A Vermont man accused of causing a head-on crash on Route 2 that resulted in serious injuries to a Rhode Island family of four last year had his $10,000 bail revoked on Thursday after testing positive for cocaine.

Javery A. Hattat will remain incarcerated after being taken into custody in Franklin County Superior Court on the order of Judge Michael Callan.

Hattat has pleaded not guilty in Superior Court to four counts of negligent operation of a motor vehicle while under the influence of drugs resulting in serious bodily injury; four counts of reckless assault and battery with a dangerous weapon; negligent operation of a motor vehicle; possession of a Class B substance (cocaine); and failure to stay within marked lanes. He posted bail in Greenfield District Court and was ordered to have no contact with the alleged victims of the crash. His case was transferred to Superior Court due to its severity. His bail also was transferred.

Hattat allegedly fell asleep at the wheel near Longview Tower on Route 2 in Greenfield on March 12 and crashed into a vehicle carrying a family headed home from a Berkshire East Mountain Resort ski trip. Authorities allege Hattat was under the influence of drugs at the time of the crash.

When questioned by police at Baystate Franklin Medical Center following the crash, Hattat allegedly told officers he fell asleep after being up all night ingesting cocaine but that he had stopped at around “1 or 2” so as to not drive impaired, according to a police report filed by Northampton Police Officer Heather Longley. However, Longley, a certified drug recognition expert called to assist the Greenfield Police Department, wrote that Hattat did not clarify if this was 1 or 2 a.m., or 1 or 2 p.m. He also allegedly admitted he had smoked marijuana about an hour before his drive to “stay awake.”

Longley’s narrative also indicated Hattat was prescribed Suboxone, which he reportedly ingested earlier that morning.

“With all of the combined factors, the many general indicators of impairment, the admission of ingesting cannabis, Suboxone, cocaine and crack cocaine, it is apparent that this is a poly-drug use impairment,” Longley wrote in her narrative. “Although I was unable to conduct a full evaluation, I feel confident in my assessment to form an opinion.”

Hattat is represented by attorney R. David DeHerdt. First Assistant District Attorney Steven Gagne is prosecuting the case.
