A Rochester man has been charged with negligent homicide after a motor-vehicle crash in the city left two people dead.

Joshua McCarthy, 33, was arrested by police Monday.

On Sept. 19 at about 9:15 p.m., McCarthy was turning onto Washington Street in a 2017 Chevy Silverado when he crashed into a 2010 Dodge Journey driven by 64-year-old James Hughes of Barrington, according to police.

Hughes died on the way to the hospital. His wife, Suzanne Hughes, 59, was pronounced dead at the scene.

Two passengers in the Silverado were transported to Frisbie Memorial Hospital with non-life-threatening injuries.

McCarthy and a third passenger in the truck did not require transport.

Assistant County Attorney Katelyn Henmueller said Tuesday that the Silverado’s event data recorder showed McCarthy revved the engine while approaching the intersection.

“There was no braking or attempt to brake at that stop sign,” Henmueller said.

In addition to two counts of negligent homicide, McCarthy faces three witness-tampering charges. After the crash, he encouraged witnesses to falsely report events of the night to police, Henmueller said.

Henmueller said McCarthy also was charged with falsifying physical evidence charge for dumping alcohol out at the scene before police arrived.

According to their obituary, James and Suzanne Hughes were born in Lynn, Mass. James Hughes was a veteran of the U.S. Navy and worked as a professional driver. He drove a taxi, a bus and ran his own trucking company.

The couple were married for more than 40 years and had four sons — David, William, Brian and James, according to their obituary.

McCarthy was released on $10,000 personal recognizance bail. His arraignment in Strafford County Superior Court has not been scheduled.

All six charges against him are Class B felonies. If convicted, he could be sentenced to up to 42 years in prison.
