On the evening of October 13, 2015, 20-year-old Zachary Corbut was shot and killed during a targeted home invasion at a residence in the 1400 block of East Grant Road in Tucson, Arizona. Several masked intruders forced entry from the rear and assaulted two of Zachary’s 20-year-old roommates with firearms; both roommates survived. Zachary emerged from his bedroom during the attack and was shot multiple times. Tucson police found him shortly after 6:00 p.m.; emergency personnel pronounced him dead at the scene, less than a month before his 21st birthday.

No arrests have been made and no suspects have been publicly identified. The Tucson Police Department keeps the investigation open. Zachary’s mother, Ann Corbut, has publicly campaigned for leads by putting up billboards and bus stop bench signs, and the Pima County Attorney’s Office is offering a $20,000 reward for information that leads to an arrest.

If anyone knew Zachary, his roommates, or saw anything in the East Grant Road area on October 13, 2015, please share what you know with investigators.
