Two men were shot, one fatally, at a Dorchester intersection late Wednesday night, police said.

Officers responded to a report of two people shot at 138 Norfolk St. shortly before 11 p.m., Superintendent-in-chief William Gross said at the scene.

The motive of the shooting was not immediately clear early Thursday. No suspect was in custody as of 12:30 a.m. Police were still gathering information, said Gross.

“We have to come together to stop these senseless acts of violence,” he said.

Police found two victims suffering from gun shot wounds in a black SUV. One of the victims, a man thought to be in his mid-20s, was pronounced dead at the scene, police said.

The other victim, believed to be a man in his late teens, was taken to a local hospital and is expected to survive his wounds, according to police.

The slaying marks the 31st homicide of the year in Boston, said Gross.

Police were canvassing the neighborhood for witnesses and checking the area for video surveillance footage early Thursday, said Gross.

The investigation is active and ongoing, he said.
