He practiced with a firm for a while, arguing a case before the Wyoming Supreme Court. He then opened his own office. He apparently withdrew his name from the roll of registered attorneys in August, 2017.

His You Tube channel has videos with rants against the Sheriff's Dept for a traffic stop. In one video I watched, now deleted, he says he's going to run against the current Sheriff. He's wearing a Libertarian hat, but he's not a registered Libertarian according to someone from that party. I read one report that the Douglas County Sheriff's tried to have him held on a mental health hold at some point (which probably explains the contacts with various law enforcement agencies but no criminal history.) In another video, he is playing with a Yo-Yo. He's pretty obviously mentally disturbed.

The military says he was honorably discharged.

Original Post: Noon, MST

I watched the Douglas County Sheriff's noon press conference on this morning's shootings in a Highlands Ranch apartment complex in which one Sheriff's Deputy was shot and killed, four others shot and injured, and two civilians injured.

Some news articles are continuing to misreport the details provided by the Sheriff.

What the Sheriff said:

• It was not a domestic violence disturbance but a noise disturbance. Although the first 911 call they received from a neighbor led them to believe it was a domestic violence incident, when police got there they quickly figured out it was not. It was a noise disturbance. The suspect was making a lot of noise and disturbing everyone around him.
• There were two people in the apartment who were male roommates -- they were not a couple or partners. The roommate was not injured.
• One of the two, the suspect or the roommate, answered the door and let the police in. The police could tell there was some kind of unfortunate circumstance in the apartment and began investigating and speaking to both of them.
• The police were not shot instantly upon arriving. They "responded to the residence" at 5:14 a.m. After the police got into the apartment, they briefly engaged the suspect in conversation. Then the suspect barricaded himself in one of the bedrooms and began shooting. He had a rifle and shot more than 100 rounds. (The Sheriff referred to this as an "ambush".)
• The suspect was known to law enforcement in Douglas and surrounding metro areas but had no prior criminal history.
• The officers were all wearing bullet-proof vests. The first officer, Zackari Parrish, 29, was shot several times. The other four who were shot went down almost simultaneously -- and could not get to Parrish to drag him away because of their injuries and the suspect was still shooting. They managed to crawl away. They were either shot in areas the vest didn't cover or outside the coverage area. (not sure what the difference is between those.) One of the officers was female.
• There were no hostages
• A regional Swat Team came and that is who killed the suspect.
• The roommate is not a suspect and has been cooperating fully. He is not one of the civilians injured.
• There had also been a disturbance call about the apartment around 1:30 a.m. but when police got there, there was no noise.

The Sheriff said they respond to all incidents as if the person will have a gun. "This is Colorado. Everybody has a gun."

The Sheriff was clearly upset. He said this was his first loss of a deputy on duty since he became sheriff.

Highlands Ranch is a master-planned community about 20 miles South of Denver. The eastern part is in Douglas County (principal city is Castle Rock) and the Western part is in Arapahoe County. Here is the website for the apartment complex.
