Just after 5 a.m., deputies responded to the incident at the Copper Canyon apartment complex. During the investigation, shots were fired and multiple deputies were injured, the agency reported.

Douglas County sheriff’s officials released more records Friday that further fill out the picture of a man who shot and killed a deputy on New Year’s Eve and wounded four others before dying himself in a shootout with a SWAT team.

The records include police reports, audio recordings and body camera footage of incidents involving Matthew Riehl before the deadly confrontation at his apartment in the 3400 block of East County Line Road.

Deputy Zack Parrish died in the incident.

The records, released after a request by 9NEWS under Colorado’s open records law, include a series of e-mails the gunman sent to a Charles Schwab branch on Nov. 15.

A Charles Schwab security officer asked the sheriff’s office to do a welfare check on Riehl because he was sending nonsensical emails and not answering his phone.

A deputy went to check on Riehl, but the video shows that Riehl didn’t answer the door.

The materials provided to 9NEWS Friday underscore what 9Wants to Know has already reported: Riehl was known to local law enforcement, he often acted erratically, threatening the people he was dealing with – including his financial advisor and a Lone Tree Police officer who’d issued him a speeding ticket in November 2017.
