Stacey Dean Rambold, whose 30-day sentence earlier this week for the rape of a 14-year-old Billings girl who later committed suicide sparked outrage, is serving his sentence at the state prison in Deer Lodge.
Officials said Friday that Rambold, 54, was picked up at the Yellowstone County jail by a state prison vehicle Thursday morning and was driven to Montana State Prison.
Rambold has been placed in the Martz Diagnostic Intake Unit, a prison facility where new inmates are screened before being placed in a prison housing unit, said Judy Beck, a spokeswoman for the state Department of Corrections.
The screening center has capacity for about 180 inmates, who spend between 30 and 60 days there before moving to the main prison.
Beck said Rambold's sentence, even though it is for only 30 days, specified he be placed at the state's main prison.
Rambold was sentenced Monday by Yellowstone County District Judge G. Todd Baugh, who ordered the former Senior High teacher to serve 15 years at the state prison, with all but 31 days suspended, for sexual intercourse without consent.
Rambold received credit for one day previously served.
The rape occurred in 2007, when Rambold was teaching at Senior High, where Moralez was a freshman. Prosecutors said Rambold used his position to groom a vulnerable teen into a sexual relationship.
Moralez committed suicide in February 2010, shortly before her 17th birthday.
The sentence imposed Monday by Baugh, and statement he made at the hearing, have drawn international attention and criticism.
Baugh said at the hearing that the victim, Cherice Moralez, was older than her chronological age and had some control of the sexual relationship with her teacher.
A protest rally Thursday drew about 400 people to downtown Billings, where participants asked for Baugh's resignation.
