A 45-year-old man shot last month near Portland’s Oxford Street homeless shelter has died.

Portland police said Wednesday that Jack Wilson died about 7 p.m. Tuesday from injuries he sustained during a shooting on June 26. Wilson’s death is now considered a homicide, and Portland police said it will be up to the Maine Attorney General’s office to decide whether to file charges against the suspect, who has not been identified.

No additional information about Wilson was immediately available Wednesday afternoon.

At the time of the shooting, a Portland police officer was in the area of the Oxford Street Shelter – Portland’s primary emergency shelter for homeless adults – when he saw an altercation and heard gunfire. The officer ran to the area and administered first aid until the victim could be taken to Maine Medical Center, where he has been in critical condition.

Police previously said they had identified all of the parties involved in the incident but have yet to release any additional information.

The shooting is one of several violent incidents in Portland’s Bayside neighborhood that have shaken local residents already concerned about fighting, open-air drug use and other illegal behavior.

In addition to the shooting involving Wilson, two people were injured during stabbings in Bayside in June. And on July 1, an 18-year-old woman and a 30-year-old man were wounded by gunshots during an altercation near Cumberland Avenue and Mayo Street in East Bayside.

Portland police have stepped up patrols in the neighborhood in response to the rash of violent activity.
