The warden at Montana State Prison in Deer Lodge was let go Tuesday, before the end of his yearlong probationary period.
Judy Beck, a spokeswoman for the state Department of Corrections, confirmed the firing of Michael Fletcher on Tuesday afternoon.
Beck said Fletcher's hiring was announced in March but that he overlapped for a period of time with outgoing warden Leroy Kirkegard through possibly April, so it was unclear when Fletcher's official start date was.
Beck said she couldn't provide information about why Fletcher was let go.
Fletcher was most recently the superintendent of a maximum-security juvenile detention facility in Nevada.
He also served as superintendent of the Summit View Youth Facility in Las Vegas. Fletcher was chosen to reopen the troubled Nevada Department of Health and Human Services facility in August 2015 after it had been closed for the third time. Previously, he served as warden of operations at Ely State Prison, a maximum-security penitentiary in rural Nevada. Fletcher worked for the Nevada Department of Corrections from November 2010 until August 2015.
