Raul Guadalupe Ocon-Marin, 32, was sentenced to two and half years in federal prison without parole.
On Sept. 20, 2013 Ocon-Marin pleaded guilty to illegally reentering the United States.
He was convicted in 2004 of sexual abuse for having sex with a 15-year-old girl in Iowa. The girl became pregnant, but she miscarried. Ocon-Marin's legal status was revoked and he was deported to Mexico in 2005.
In January of 2013, the Buchanan County Sheriff's Department was informed Ocon-Marin was illegally living in St. Joseph, prompting his arrest for failing to register as a sex offender.
He was convicted in February 2013 and released on parole in June 2013 before being taken into federal custody.
