Two women in their 20s were killed in a single-car crash in Plymouth Wednesday night, Massachusetts State Police said.
The crash happened along Route 44 at Cherry Street.
The mother also died and the infant was taken by helicopter for injuries.
One of the women, a 20-year-old Sagamore Beach resident, was pronounced at the scene while the second victim, a 26-year-old woman, was rushed to a Plymouth hospital where she later died from her injuries, State Police wrote in an e-mail.
"I'm traveling eastbound on Route 50 toward the Bay Bridge, and there was just a auto coming head-on down all three lanes eastbound". Murphy was declared dead at the scene.
The driver of the Mercedes, Robert Skidmore, 66, of Cape St. Clair, was trapped inside his vehicle. The 14-month-old boy with her is still undergoing treatment at Johns Hopkins Hospital.
State police said that thanks to 911 calls just before the fatal crash, investigators have been able to narrow down the possible point of entry to the highway. Skidmore was driving a silver 2016 Mercedes SUV eastbound on Route 50 when he was hit head on by a vehicle traveling in the opposite direction.
