Police arrived around 8:45 p.m. Wednesday at the home on the 2800 block of 46th Street. Paramedics treated the victim's wound but were ultimately unable to save him. He was pronounced dead at the scene.
Investigators believe the man got into a fight with someone else living in the home, and it escalated, leading to the fatal stabbing. They had not yet determined what the fight was about.
A person of interest in the case had already been identified and was being questioned by police Wednesday night. The victim's identity will not be released until his family has been notified.
