LONGMEADOW, Mass. (WWLP) – Two people are dead after a serious accident involving two trucks during a police chase on Route 5 in Longmeadow Thursday morning.  

The Hampden County District Attorney identified the two people killed in the accident as 47-year-old David Cersosimo of Rocky Hill, CT, and 59-year-old Daniel Nacin of Enfield, CT. Both men were taken to Baystate Medical Center where they later died.

Enfield Police began chasing a pick-up truck driven by Cersosimo on Route 5 in Enfield after he allegedly failed to stop and had “sideswiped” a vehicle around 11:00 a.m.

Hampden County District Attorney’s Office spokesman Jim Leydon said Cersosimo proceeded on Route 5 into Longmeadow where he collided with a US Postal Service truck, driven by Nacin, in the Booth Road and Longmeadow Street area.

USPS spokeswoman Maureen Marion told 22News Nacin was a 40-year-employee of the Postal Service working out of the Enfield, CT Post Office.

The Massachusetts State Police accident reconstruction team and homicide investigators from the Hampden DA’s Office are involved in the investigation. Longmeadow and Enfield police are also assisting.

“This is an open and active investigation,” the Hampden DA stated in a news release sent to 22News.
