A Warren County man found guilty of incest and second-degree rape has been sentenced to 22 years in prison.A Warren County jury found 46-year-old John P. Mahan guilty of the crimes June 28.During a Sept. 5 sentencing hearing, Presiding Judge Wes Dalton sentenced him to 15 years of incarceration for the rape conviction and seven years for the incest conviction.The sentences will be served consecutively in a Missouri Department of Corrections facility, and Mahan will receive credit for the 20 months he has spent in Warren County’s jail.The actions leading to Mahan’s conviction reportedly occurred at his residence on Ridgewood Drive south of Wright City. The Warren County Sheriff’s Department was contacted and began an investigation in December 2013, according to the sheriff’s office.Warren County Circuit Court records indicate that Mahan was not charged with a crime until almost two years later, in October 2015.Mahan has been held in jail since his arrest on that charge. His attorneys asked for a bond reduction several times, but were denied.County Prosecuting Attorney Kelly King previously told The Record that Mahan is a prior and persistent offender, leading to a longer prison sentence than he might otherwise have received.Court records show Mahan is also facing two charges of statutory rape and one charge of statutory sodomy in Franklin County. Although the charges in that case were issued in 2011, Mahan was not taken into custody until October 2013, according to court records.In November 2013, the Franklin County Circuit Court reduced Mahan’s bond from $100,000 to $25,000 with a 10 percent cash or surety accepted.He posted bond in early December 2013, about two weeks before the rape and incest were reported in Warren County.A hearing is scheduled for Oct. 24 in Franklin County in front of Circuit Judge Ike Lamke.John P.
