A Colorado Springs man died early Sunday in Denver's downtown jail after a suicide attempt two days earlier.
Thomas Howard was pronounced dead at 1:34 a.m., three days after being booked into the Denver Sheriff Department facility.
He had two arrest warrants out of El Paso County for violating his probation, said El Paso County Sheriff's office spokeswoman Jacqueline Kirby.
According to Colorado voter registration records, Howard lived in Colorado Springs in 2011.
The Denver Sheriff Department says Howard tried to commit suicide on Christmas Day and was found by a deputy doing rounds.
Simon Crittle, spokesman for the Denver Sheriff Department, said the death is under investigation per standard protocol. Crittle said deputies in the pod where Howard was being held check on inmates twice an hour.
Colorado Bureau of Investigation records show Howard was arrested for the warrant Wednesday by Denver police.
Howard had a long criminal record in Colorado dating to 2010, CBI records show.
According to court documents, Howard pleaded guilty in October 2013 to second-degree kidnapping involving a sexual offense and robbery in Colorado Springs.
He was sentenced to 90 days in jail and a 4-year probation.
