Gunfight in Tucson, Police Officer Critically Wounded

Story here. The TPD officer who was shot in the head with a rifle is not doing well, and is not expected to live. Two Pima County Sheriff’s deputies also received relatively minor gunshot wounds.
This is a terrible tragedy. My sincere thoughts and best wishes go out to the wounded officer and his family.
The only good thing that can be said is that the suspect is in custody and will have his day in court, as opposed to having escaped and be at large.
Details about the specific type of weapons used in the gunfight and found in the suspect’s vehicle are not immediately available, though several news organizations suggest the primary weapon involved was an “assault rifle”. Considering the media’s lack of knowledge of firearms-related topics, this term could very well mean “any gun at all”.
More information as I get it. If anyone here was a witness to the events or has additional details, please contact me.
UPDATE: Officer Hite succumbed to his wounds at the hospital, reports the Tucson Citizen. The suspect has been re-booked on first degree murder charges. The two sheriff’s deputies who were wounded were released from the hospital today as well, so there’s some good news.
