CHEYENNE, Wyo. (AP) - A Cheyenne man is heading to prison for choking his pregnant girlfriend in 2013.

Nikko Johnson's probation was revoked Monday and he has been ordered to serve a sentence of three to five years in prison.

Johnson had admitted to being kicked out of the Laramie County Drug Court program and was set to be sentenced for that violation on Dec. 14. He did not show up for that hearing.

Days later, he was arrested for a separate matter and charged with strangulation of a household member for choking his ex-girlfriend again on Dec. 18. She did not die from the assault.

The more recent charge is working through the court system.
