It was a deadly weekend on the state roads as travelers made their way around and through Connecticut, according to State Police statistics released Monday night.

Over the weekend there was a total of 260 accidents, including four involving fatalities and 18 others with injuries, 70 arrests for driving under the influence, 978 infractions for not wearing a seat belt and 2,013 speeding tickets issued, according to state police.

The Memorial Day enforcement used additional troopers who manned sobriety checkpoints, targeted DUI and aggressive drivers and added patrols across the state, according to State Police spokesman Lt. J. Paul Vance.

"Motorists are reminded as summer continues, if they see a suspected drunk driver, call 9-1-1, as this is a true emergency," said Vance. "Help the State Police keep the highways and roadways of Connecticut safe."

The four fatal crashes included one late Monday on Interstate 95 southbound in Orange involving a tanker truck and a car as holiday travel wrapped up. One person, the passenger of the car, was killed, and the driver severely injured after the driver of the car lost control and struck the jersey barrier in the center median and then collided with the tanker.

State police said Jose Nunez, 33, of Warrington, Penn. died in the crash. The driver of the car, Johnny Nunez, 18, of Providence, was taken to Yale-New Haven Hospital with a head injury. The driver of the truck and a passenger who was in the sleeper portion of its cabin were not injured.

The other three fatal crashes occurred on Saturday and all happened in the eastern portion of the state.

The first crash happened just after 1:30 a.m. in Groton on I-95 southbound near exit 88. David Reidy, 27, from Rhode Island, lost control of the minivan he was driving and went off the side of the roadway, clipping the guardrail in the process and flipping over. Reidy was injured and his passenger, Laura Kavavanjian, 27, of Long Island, N.Y., was killed.

A few hours later, just after 6 a.m., Eric Mohamed, 18, of Manchester, died in Bolton on Route 85. Few details of that crash have been released by police and it remains under investigation.

The third fatal crash happened in Pomfret Saturday afternoon. A Houston man, 23-year-old Christopher Corona, died after his motorcycle crashed into a car head on after failing to make a turn correctly, police said. A passenger, 21-year-old Haddam resident Kristin Pare, was taken to a New London hospital to be treated for unknown injuries.

Last year, one person died in a Memorial Day weekend crash.
