Frederick Buettner, 42, of St. Louis, MO, was sentenced today in the U.S. District Court for the Southern District of Illinois to 24 months in prison, followed by 5 years of supervised release, on one count of Failure to Register as a Sex Offender. His sentence was ordered to run consecutively, that is, in addition to his sentence for violating the terms and conditions of mandatory supervised release on his Illinois sex offense.

Buettner was placed in a halfway house in East St. Louis, Illinois. In July 2013, Buettner cut his electronic leg monitor off and absconded. On June 30, 2014, he was apprehended in St. Louis, Missouri.
The case was investigated by the U.S. Marshals Service. The case was prosecuted by Assistant United States Attorney Laura Reppert.
