Montana prosecutors are appealing the 30 day sentence a judge gave a former teacher after he admitted raping his 14 year-old student, who then took her own life.
The state attorney general described the sentence as "illegal," and the judge now concedes, he may have been wrong.
54 year-old Stacy Rambold pleaded guilty to one count of rape and was sentenced to 15 years in prison with all but 31 says of it suspended.
Will the appeal mean more time behind bars?
