Braintree high schooler and Dorchester teen killed in early Sunday shooting, investigators say

A Braintree High School student and a teen from Dorchester were killed in a shooting in Braintree early Sunday morning, according to a statement from the Norfolk district attorney's office.

Police found Jahzier Porter, 16, and Jayden Santos-Andrade, 19, suffering from gunshot wounds in a parked car outside of Porter's home around 1:30 a.m. on Sunday, prosecutors and police officials said.

Police, fire department personnel and paramedics started life-saving measures and transported the teens to a local hospital, where they died, police said in a statement.

“We have two families grieving today,” said Norfolk District Attorney Michael Morrissey Sunday in a statement. “We have detectives in the field from Braintree and State Police trying to gather evidence of what happened and who may have been involved."

No arrests have been made. Investigators said they do not believe there is an ongoing threat to public safety.

Police urge anyone with information about the shooting, or doorbell camera footage in the neighborhood between 1 and 2 a.m. Sunday, to contact state police detectives assigned to the Norfolk district attorney's office at 781-830-4990, or the Braintree police at 781-794-8620.
