State police are investigating a tractor trailer crash that they say killed the vehicle's two occupants.
Authorities say the vehicle was engulfed in flames when troopers responded to the crash in Greenfield, Mass., at about 3 a.m. Sunday.
It happened on the northbound side of Route 91, prompting police to shut down part of the road for several hours.
Police say both victims lived out-of-state, and they didn't immediately release their identities so their families could be notified first of their deaths.
Authorities say the tractor trailer crashed into the median between exits 27 and 28.
