John Leonard Smith, 62, had been arguing with the victim inside their home in the 2000 block of North Norhurst Way, police said, when the argument escalated into a fight. Smith followed the victim — who was not named — outside and stabbed him once in the upper body, police said.
Officers were dispatched at 6:28 p.m., and the man was taken to a hospital for treatment. He was expected to survive, police said.
Smith, who was arrested at the scene, has been charged with attempted first-degree murder and related charges. He is held without bail at the Baltimore County Detention Center.
No lawyer was listed for Smith in Maryland court records.
