Police say the domestic disturbance that Boston police were responding to when two veteran officers were shot and wounded may have started as an argument over the thermostat.

Police Commissioner William Evans says the officers were called Wednesday night to an apartment in the East Boston neighborhood, where 33-year-old Kirk Figueroa was allegedly threatening his roommate with a knife.

Evans says the roommates may have been fighting over the thermostat, but there likely were other issues.

Police say when the two officers entered the home they were shot by Figueroa, who was armed with a tactical shotgun and wearing body armor. Figueroa was then shot and killed by other officers.

The injured officers have been identified as Richard Cintolo and Matt Morris. Both are in critical condition, but are recovering.
