Evergreen High suspect's social media includes posts about Columbine

Driving the news: The social media accounts believed to belong to the alleged shooter Desmond Holly, reviewed by Axios Denver and described by local media, referenced the 1999 Columbine High School attack and included a photo of a revolver and ammunition about an hour before the shooting.

• In one posted photo, the suspect appeared in a black T-shirt with the word "wrath" written in red across the chest, similar to what one of the Columbine shooters wore in 1999.
• Other posts depicted antisemitic and racist content, according to reports, part of what authorities have described as his radicalization from an "extremist network."

What they're saying: "We want to at least give you that much about maybe [the] mindset for him," Jacki Kelley, a spokesperson for the Jefferson County Sheriff's Office, told local media Thursday.

Between the lines: Authorities confirmed last week the suspect used a revolver in the shooting, but declined to comment further about the social media posts.

What we're watching: Federal and local authorities are continuing to investigate the shooting and mapping Holly's movements before and during the attack.

• One open question, investigators say, remains how Holly obtained the gun.
