An elementary school librarian is accepting accepted a lengthy prison term as part of a plea agreement for sex offenses he committed upon six young boys in Bullhead City. Michael Oakleaf, 43, pled guilty to one count of child molestation and five counts of attempted child molestation. Prosecutor Doug Camacho said three of the victims were Oakley’s adopted brothers and three others were foster children of his parents. The crimes, mostly involving improper touching activity, occurred between 2005 and 2012, involving victims four to 12 years of age. The agreement requires Mohave County Superior Court judge Rick Williams to order a 20 year prison term at sentencing December 4. Oakleaf would serve probation and be required to register as a sex offender for the rest of his life upon prison release.
