The Laramie County Sheriff's Office is asking for the public's help in finding 27-year-old Steven Guille.

"He's being sought for a probation revocation," said Lt. Don Hollingshead.  "The original incident that this stemmed from was a domestic violence call from back in February of 2012 where during the altercation he used a knife to attack his then-girlfriend."

Guille is a 6-foot-1 male weighing 200 pounds, with blonde hair and blue eyes.​

Anyone with information on Guille's current whereabouts is asked to call the Laramie County Combined Communications Center at (307) 637-6524 or Crime Stoppers Silent Witness at (307) 638-TIPS.

"Let's work together to get this person off the streets," said Hollingshead.
