Two men and a teen charged with murder on Southampton Street

UPDATE: Victim identified as Nicholas Martinez, 22.

Three Hyde Park residents - one wearing a court-ordered GPS device for a drug conviction last year - were ordered held without bail today on charges they murdered a man in another car last night, the Suffolk County District Attorney's office reports.

Shakeem Johnson, 22, Jaquan Hill, 19, and Raymond Concepcion, 15, all of Hyde Park, were arraigned on murder charges in Roxbury District Court for an incident shortly before 7 p.m. outside 85 Southampton St.

According to the DA's office, the victim and an acquaintance were stopped in a car there, several car lengths ahead of the suspects. One of the suspects got out of their car, walked up to the victim and opened fire, shooting several rounds into the car. The man was taken to nearby Boston Medical Center, where he was pronounced dead. The DA's office adds:

Also stopped in traffic was a Boston Police detective. That detective heard multiple shots, saw the individual getting into the back seat, and watched the car begin to leave the scene. He gave chase and briefly boxed the suspect vehicle in, but the vehicle was able to speed off.

The suspects fled onto the Expressway south, where State Police picked up the chase, eventually boxing them in near the Freeport Street exit. An extensive foot search, which slowed or shut the southbound side of I-93 for much of the night, resulted in the alleged murder weapon being found on the side of the road.

Johnson was convicted December on a charge of possession of cocaine with intent to distribute, the DA's office says. He was riding shotgun, Hill was driving and the teen was in the back seat, the DA's office adds.

Innocent, etc.
