Authorities in Springfield are investigating an apparent homicide in the northwest part of the city.

One man is dead, and at least two other people suffered injuries during a knife fight in the 1300 block of Mt. Vernon Street about 4 p.m. Sunday.

A woman, who appeared to be bleeding from her leg, was treated at the scene and another woman said she was stabbed in the arm.

Corporal Matt Brown says the man is being questioned about the incident that is being investigated as a suspicious death.  “It’s a possibility it could be upgraded to a homicide at some point,” he said.

On July 12th authorities were called to a murder/suicide four houses away from Sunday's stabbing.
