Officials in Colorado had been contacted in November regarding the mental state of Matthew Riehl, who killed a deputy and wounded four others on New Years’ Eve.
Riehl fired more than 100 shots in his “suburban Denver apartment before he was killed by a SWAT team on Sunday,” according to police.
A former school that Riehl attended, the Wyoming College of Law, had sent a warning to students and staff about him in November, telling them to contact campus police if they saw him or his car near campus.
Police were also notified. (source)
