Around 6:20 pm Companies 1 & 3 were dispatched to Route 8 South between exits 13 and 12 for a reported MVA. Upon arrival of Squad 1, it was determined multiple people were ejected and 1 was heavily entrapped in the vehicle. Crews worked for over 90 minutes to free the trapped individual who was then transported by EMS with serious injuries. Unfortunately 1 person succumbed to their injuries at the hospital. The Connecticut State Police is currently investigating the incident and anyone with information is asked to call them.
