A man wanted in a Cleveland homicide and a rape in Summit County was arrested following a SWAT standoff in Dayton Monday.

An investigation into the whereabouts of 50-year-old John L. Armstrong led the Northern Ohio Violent Fugitive Task Force and Southern Ohio Fugitive Apprehension Strike Team to an apartment building in the 3600 block of Delphos Avenue.

When task force members approached the apartment building, a round was fired from inside the building toward officers, the U.S. Marshals Office said.

As a result, Dayton police issued a shelter in place advisory, and SWAT and hostage negotiation team members responded to the area.

The advisory started shortly before 11 a.m. and ended around 3:30 p.m.

SWAT eventually arrested Armstrong, who is being held in the Montgomery County Jail.

He will remain in custody in Dayton until he is extradited to Northeast Ohio.

“This violent fugitive fled from northern Ohio to Dayton and then took drastic actions that put our task force members’ lives at risk,” said U.S. Marshal Michael Black. “Our task force members are experienced and well-trained to operate in chaotic and dangerous situations like (Monday).”

Black said an officer had a minor laceration on their leg, but no one was seriously injured.

Armstrong is wanted in the death of 46-year-old Juvar King. King was reported missing on Feb. 4 after he didn’t pick up his daughters, according to the U.S. Marshals Office.

The East Cleveland Police Department reportedly found King shot in the head on March 17.

Armstrong also had a warrant for the rape of a juvenile in Summit County, according to the U.S. Marshals Office.
