Officers and detectives responded to the scene and did not locate any victims.

"Police recovered seven 9mm shell casings near the back of the building and logged them into evidence at headquarters," said police spokesman Darren Duarte.

365体育平台Witnesses told police they saw a blue BMW speeding away from the scene.

"Investigators believe the man who had a gun fired on a white Volkswagen as it was leaving the parking lot," Duarte said. "Detectives located the Volkswagen which was struck by gunfire."

A sheriff's deputy with the Plymouth County Bureau of Criminal Investigation responded to photograph the scene and document evidence.

The shooting was the fourth in the span of three days in the city, with the other three shootings occurring on Saturday.

365体育平台The first occurred at about 4 a.m. on Saturday. ShotSpotter alerted police to numerous rounds of gunfire in the area of 7 Fletcher St. Officers located 11 9mm shell casings on nearby Ames Street and found that the gunfire hit the rear windshield of a parked and unoccupied Honda sedan that was behind 135 Ames St.

Later that day, at about 3:54 p.m., gunfire erupted in broad daylight outside the busy Westgate Mall. Officers responded to the parking lot at 200 Westgate Drive, near Liam’s Home Furniture and Planet Fitness, and found seven 9mm shell casings at the scene. Three bullets struck an unoccupied Infiniti sedan that was parked outside the mall, but no one was injured.

Police said they believed the shooter outside Westgate Mall was likely targeting someone in a moving vehicle.

A witness told police that a black pickup truck with tinted windows fled toward Reynolds Memorial Highway.

A short time later, at about 3 p.m., Mass. State Police received a report that a person was firing a gun out the window of a dark-colored pickup truck that was traveling on Route 24 northbound in Randolph.

"The caller reported that the shooter was firing at other vehicles," state police spokesman David Procopio said in a statement Sunday.

365体育平台Police are investigating whether the two incidents are connected, but have not yet determined if there is a definite connection.

The third shooting on Saturday inside the city occurred at about 8:50 p.m. Police responded to the area of 117 Belmont Ave. and located a male victim, later identified as 22-year-old Ailson Barbosa of Brockton, in the area of a stairwell to the home. Barbosa was rushed by ambulance to Good Samaritan Medical Center, where he died.

The fatal shooting was the city's first homicide of the year.

A spokeswoman for the Plymouth County district attorney's office did not respond to a request for comment on Tuesday regarding the ongoing murder investigation.

365体育平台No one has been arrested yet in connection with Barbosa's murder.

As for Monday night's shots-fired incident outside Domino's, the investigation remains ongoing.

"Detectives are following up on leads and continue to search for the suspects," Duarte said.
