Police have identified the man killed Tuesday morning in a triple shooting in Boston's Mattapan neighborhood.
Authorities said Yashua Amado, 29, of Mattapan, was one of three men officers found suffering from gunshot wounds at about 9:48 a.m. on Deering Road.
Amado was pronounced dead at the scene while the two other victims, also in their 20s, were taken to area hospitals.
Police said they are not releasing the identities of the two other victims.
Investigators believe the men were shot inside a car and then got out of the vehicle.
No arrests have been made in connection with the shooting.
At the scene Tuesday, Gross made a public plea for residents to come forward with information to help detectives solve the deadly shooting.
"We need to send a message that it's not acceptable in the city of Boston," he said.
He said that despite Massachusetts having some of the toughest firearms laws, there are still too many guns on the streets, vowing that "until we have unilateral gun laws in the New England states and southern states as well, we'll continue to fight this battle."
