A verbal dispute in the hallway of the Martin Luther King Building apartment complex at 55 N. Fifth Ave. in downtown Tucson turned fatal just before midnight on April 29, 2021. Andre Michael Lee, 57, was found with gunshot trauma after officers responded to a report of a shooting and was pronounced dead at the scene. Investigators say an argument preceded the shooting and the assailant fled.

Police identified a suspect the next day. Joseph Paul Cavanaugh, 32, was arrested and charged with first-degree murder and first-degree burglary and was booked into the Pima County Detention Center; investigators indicated additional charges were possible. If anyone saw the confrontation in the hallway or has information about what led up to the argument, please share what is known with authorities.
