SPRINGFIELD, Mo. – A Missouri sex offender has been sentenced in federal court for receiving and distributing child pornography, according to the United State’s Attorney.

Bill Lawrence, Jr., 57, was sentenced by U.S. District Judge Roseann Ketchmark on April 5, to 15 years in federal prison without parole. The court also sentenced Lawrence to 15 years of supervised release following incarceration.

Lawrence, who pleaded guilty on Aug. 28, 2018, has prior convictions for possessing child pornography and promoting child pornography.

According to court documents, the investigation began with two CyberTips from the National Center for Missing and Exploited Children. Lawrence had attached images of child pornography to at least two emails that were sent from his Google account. The images depicted prepubescent children being sexually abused or in sexual poses.

Law enforcement officers executed a search warrant at Lawrence’s residence and seized his cell phone, which contained multiple images of child pornography. Lawrence admitted to officers that he used the Chat Hour application to both receive and distribute child pornography over the internet.
