An Oklahoma inmate who used a smuggled cellphone from behind bars to coerce a 12-year-old South Florida child into producing child sexual abuse material was sentenced Wednesday to life in federal prison. “Even a lengthy prison sentence for rape did not stop Jeffrey Allen Holden from seeking out and sexually exploiting another vulnerable victim,” U.S. Attorney Jason A. Reding Quiñones said. “From his prison cell, he used a contraband phone and a false name to manipulate a 12-year-old child into producing CSAM. After the mother contacted police, investigators examined the child’s phone and found child sexual abuse material exchanged in direct messages. At the time he was locked up at the Howard McLeod Correctional Facility in Oklahoma, serving a 25-year sentence for rape.
