A Pinetop-Lakeside (Arizona) officer was brought to a hospital for treatment after being injured in a deadly shooting overnight. 

According to Pinetop police, officers were called to a Lakeside home around 10 p.m. Sunday night to do a welfare check. A Tucson woman called police, worried that her son, Glenn Southwood Jr., was intoxicated and had threatened to shoot his wife. 

Officers responding to the home found Southwood with a firearm who then began firing at officers. Officers returned fire and Southwood barricaded himself inside the home. 

One of the officers was hit by the suspect's gunfire above the knee. He was cared for on-scene by fellow officers and concerned citizens before he was flown to a Phoenix-area hospital.

Tactical teams were called to the home to try to make contact with Southwood. Around 3 a.m. Monday, police deployed a K-9 officer into the home. The K-9 was attacked by a pit bull and the pit bull was then killed.

Southwood was later found dead on a side porch of the home. 

Police say the injured officer is out of surgery and is expected to make a full recovery. The injured K-9 officer is being treated at a veterinarian.
