The Saturday night shooting at Jefferson Park was committed by several people, according to at least five witnesses, Officer James Green said in a report released today by Cambridge Police.

The crime is being investigated as assault to murder, according to the report. During the investigation, a victim of a gunshot was reported at Mount Auburn Hospital, it said, confirming a report Sunday.

One suspect appeared to be limping as he jumped into a gray sport utility vehicle that sped down Rindge Avenue toward Massachusetts Avenue. There were three additional suspects, one in a white shirt and one in all dark clothing, who walked quickly to Rindge Avenue and turned left toward the area’s public housing towers. The race of the suspects couldn’t be ascertained, the report said.

There had been three to four shots fired shortly after 9 p.m. after a “loud disturbance,” witnesses said, and one gunshot had gone through a window. A half-dozen officers and detectives search the area for shell casings and talked with people the area, Green said. Another witness said there had been 10 shots fired.

One bullet “penetrated his double-pane window and struck above the left corner of the rear kitchen door and bounced out,” Green said, referring to one of the people caught up in the shooting. Then, referring to a second person, “The caller was sleeping in the bedroom and was awakened by the commotion outside her window and called [Emergency Communications] when the bullet hit the living room window. No injuries were reported by the occupants.”

Update: A press release from citizenobserver.com says the victim, a 32 year old Cambridge man, was treated for a single gunshot wound to the buttocks. People with information on the shootings are urged to call (617) 349-3370.
