Two people were killed and three others were seriously injured in a head-on crash in Douglas County on Sunday and a driver also died in Larimer County after hitting an embankment. A 34-year-old man died when his car rolled over Saturday in El Paso County. On Friday, a man died after being thrown from his SUV after going off the road in Fremont County.

The state patrol’s leader, Col. Matthew Packard, said in a tweet that he was “struggling between anger, frustration and heartbreak” over the crashes and that they each were preventable.
