The suspect in a Portland killing who was shot by police has died.

Brian Oliver, 41, of Portland succumbed to his wounds at Maine Medical Center on Thursday, according to Brad Nadeau, a spokesperson for the Portland Police Department.

Officers Joseph Lowe and David Moore went to a Colonial Road residence about 8:16 p.m. on Sept. 21 after getting a call about a disturbance there.

A tenant met the officers and escorted them inside, but then the tenant, who was ahead of Lowe and Moore, ran back toward them, screaming, Nadeau said at the time.

Inside Lowe and Moore found Oliver allegedly assaulting 69-year-old Mark Tschamler, according to Nadeau.

Oliver allegedly didn’t obey commands to drop his weapon, and the officers shot him.

Oliver was taken to Maine Medical Center, while Tschamler died at the scene.

Oliver was poised to face a murder charge, but no charge had been filed because of his injuries and condition.

Lowe and Moore were placed on administrative leave, as is standard procedure. The Maine attorney general’s office is investigating, as is standard procedure whenever law enforcement officers use deadly force in the state.

It was the second police shooting in the Forest City in less than a month. On Aug. 27, Portland police shot and killed 37-year-old Jacob Hastings at the Casco Bay Lines ferry terminal on Commercial Street after a string of armed carjackings.
