HIGHLANDS RANCH, Colo. -- A man identified by a law enforcement official as the gunman who killed a Douglas County sheriff's deputy and wounded six others early Sunday posted repeated online rants against law enforcement in the area.
The sheriff's office identified 37-year-old Matthew Riehl as the man who shot the four deputies, a SWAT police officer and two civilians as they responded to a noise complaint at the apartment in Highlands Ranch.
A YouTube user identified as Matthew Riehl posted a video on Dec. 13 calling for the firing of Douglas County Sheriff Tony Spurlock and railing against him in highly personal terms.
Riehl wore an Iraq combat veteran hat in the video critical of the sheriff. He served briefly in Iraq.
Riehl graduated from the University of Wyoming College of Law in 2010.
A statement released by university said that campus police have been investigating Riehl's social media posts that mention the school by name.
The statement also said campus police are cooperating with Colorado law enforcement agencies.
