A teenage girl was killed and several others injured after a car crash Saturday night in Weymouth.

The crash happened at around 11:15 p.m. on Union Street. Police said a 16-year-old was driving an SUV when they somehow lost control and hit several cars, a tree and then a telephone pole. The SUV then came to a stop on firefighter Steve Rodriguez’s lawn. The four victims were taken to South Shore Hospital, where 15-year-old Kate McCarthy was pronounced dead.

Rodriguez said the sound of the crash woke him up.

"I was in bed and we heard boom, a collision and impact," said Rodriguez.

Rodriguez said he and some of his neighbors tried to help the victims. He said McCarthy had severe head and face trauma and he performed CPR but was unable to save her.

McCarthy and the other occupants of the car were students at Archbishop Williams High School in Braintree. Friends gathered at the crash scene to leave flowers and messages for the victims. 

The school issued a statement, offering their thoughts and prayers, and announced a schoolwide prayer service will be held on Monday. Grief counselors will also be available at the school throughout the week.
