State Police say a trooper saved a driver who had no pulse after a crash on Interstate 95 in Westwood late Monday night. Investigators say a 2015 Honda CRV was hit from behind by a 2002 Honda Odyssey minivan in the northbound lanes around 9:30 p.m. Both vehicles slammed into the guardrail and ended up on the right side of the highway. The driver of the minivan, a 33-year-old man from Westwood, reportedly had no pulse after the crash, according to State Police. “Sergeant Pardo Montago immediately began CPR and continued until Westwood EMS arrived. The man was then transported to Norwood Hospital for treatment of serious injuries,” police said in a statement. A passenger in the minivan, a 53-year-old man from Waltham, and the CRV driver, a 55-year-old woman from Needham, were both treated at Beth Israel Deaconess Hospital in Needham for minor injuries. No names have been made public. No charges have been filed at this point in the investigation.
