Police are seeking help from the public on shooting and stabbing incidents Wednesday in different parts of Cambridge — the stabbing on Rindge Avenue, near Alewife, at 9:36 p.m., and the shooting on Columbia Street near Cambridge Street a little more than three hours earlier.

It was the victim, a 34-year-old man, who left where he was shot in the abdomen and called 911.

Cambridge Fire Department Paramedics treated the victim, who was conscious, and took him to a nearby hospital for emergency surgery.  Police, meanwhile, talked to residents of the area and searched the crime scene, finding shell casings, a handgun believed to be involved in the shooting and “other evidence,” a police representative said. An Arlington police dog unit that was in the area helped Cambridge officers.

It is believed the shooter ran toward Citizens Place. “All early indications are that this was not a random shooting incident, but a deliberate and targeted event. The circumstances leading up to this incident are still being investigated and detectives are following up on strong investigative leads,” police said.

The Columbia Street shooting, which took place at 6:23 p.m., comes less than two weeks after the Jackson Street shooting of a Quincy man that was also considered as being possibly “deliberate and targeted.” The shootings happened far apart and are not considered related, police spokeswoman Emily Wright said Thursday, noting that the nature of the latest shooting hasn’t even been determined.

Wednesday’s shooting victim is listed in stable condition. At last report, the Quincy man had survived surgery after being shot multiple times in the chest and was also in stable condition, Wright said.

The stabbing was determined to have resulted from a fight, not random violence, police said. The argument and chest stabbing took place in Jefferson Park, and the 21-year-old male victim went to the Ferro’s Food Town grocery store, where someone called 911 for him. Cambridge Fire Department Paramedic Squad treated him and took him to a nearby hospital, where he is listed in serious but stable condition.

In investigating, detectives have come to believe the victim was under a no-trespassing order issued by the Cambridge Housing Authority.

People with information on these incidents are asked to call the Cambridge Police Department and Deputy Superintendent Les Sullivan at (617) 349-3370.
