A 21-year-old Cheyenne man entered guilty pleas on Friday in three pending cases in Laramie County District Court.

As part of a plea agreement, Vincent A. Ramirez plead guilty to interference with a peace officer-injury and amended charges of manslaughter and sexual battery.

Ramirez was charged with interference with a peace officer-injury and interference with a peace officer-resist in December 2016 after "mule kicking" a Cheyenne police officer.

A jury in June 2017 found him guilty of resisting arrest, but was "hung" on the felony charge.

While awaiting a retrial and sentencing in that case, Ramirez was charged with second-degree murder in the July 2017 stabbing death of 18-year-old Ian Dangler and the attempted second-degree murder of 20-year-old Camilo Olivas.

Ramirez reportedly stabbed the men with a knife after getting into a fist fight with them over his ex-girlfriend.

In November 2017, Ramirez was slapped with three counts of second-degree sexual abuse of a minor after police discovered he'd engaged in sexual intercourse with a 13-year-old girl between May 15-20, 2017, while he was 19 years old.

In exchange for his guilty pleas, the state agreed to dismiss all of the charges -- except for the interference with a peace officer-injury charge -- and is recommending that the sentences in the cases run concurrently.

Ramirez is facing a sentence of up to 31 years. His sentencing date will be set as soon as a presentence investigation is complete.
