Albuquerque firefighters battled a fully-involved house fire late Sunday night in northwest Albuquerque. It happened around 10 p.m. at a home near 2nd Street and La Plata. KOB was on the scene until the early morning monitoring the situation that involved both Albuquerque Police and Firefighters. A woman on scene told KOB that her son was living in the home with a roommate. She says her son called her and said that the roommate had pulled a gun on him and later set the home on fire. KOB is working to get information from police on this incident.
