ENFIELD, CT (WFSB) -- Two people were killed in a crash that happened on the Connecticut and Massachusetts border on Thursday.
A truck that Enfield officers were trying to stop was involved in the crash just over the Massachusetts border on Thursday morning.
The crash, which also involved a mail truck, happened just over the state line into Longmeadow on Route 5 around 11:30 a.m.
A spokesperson for the United States Postal Service identified the mail carrier who died as Dan Nacin.
Nacin is described as a 40-year employee of the Postal Service, working out of the Enfield, CT Post Office.
The Hampden District Attorney's Office identified the driver of the truck as David Cersosimo, 47, of Rocky Hill.
The Enfield police chief said officers were trying to stop Cersosimo prior to the crash, near Route 5 and Bridge Street.
Officers had observed the driver failing to obey road signs, and appeared to be intoxicated.
Then, officers tried again farther down the road at Elm Street.
While Enfield police wouldn't comment if the chase crossed state lines, it appears the driver traveled 4 miles from the first traffic stop to the crash site.
At the crash scene, on Longmeadow Street and South Avenue, mail and packages were seen scattered everywhere following the collision, along with pieces of the mail truck.
Eyewitnesses described the moments leading to the serious wreck.
"It went through the red light at a high rate of speed, maybe 50 to 60 miles an hour and it crashed into the mail truck," said Justin Anstett. "It dragged the mail truck from the red light where it is now, maybe 20 yards or so."
Neighbors nearby said it sounded like an explosion.
