WASHINGTON – William Edwin Allaun IV, 44, of the District of Columbia, was sentenced today to 60 months in prison in connection with his possession of child sexual abuse material depicting images of the rape and torture of young children, announced U.S. Attorney Jeanine Ferris Pirro.
Allaun pleaded guilty on Dec. 15, 2025, before U.S. District Judge Royce C. Lamberth to one count of possession of child pornography. In addition to the 60-month prison term, Judge Lamberth ordered Allaun to serve 10 years of supervised release. Federal prosecutors had requested a 78-month prison term, followed by 15 years of supervised release. Judge Lamberth also ordered Allaun to register as a sex offender.
According to court documents, in May 2025, Allaun was added to a group chat on an encrypted messaging application that was used to distribute child sexual abuse material. Allaun received multiple videos depicting the sexual abuse of prepubescent children and expressed interest in receiving additional material.
A search of Allaun's residence in July 2025 led to the recovery of additional videos depicting child sexual abuse material, sent through the same group chat.
As part of his sentence, Allaun agreed to forfeit an iPad and an iPhone seized during the investigation. He also agreed to pay restitution to the victims.
This case was investigated by the FBI’s Child Exploitation and Human Trafficking Task Force. It was prosecuted by Assistant United States Attorney Richard Kelley.
It was brought as part of the Department of Justice's Project Safe Childhood initiative. In February 2006, the Attorney General created Project Safe Childhood, a nationwide initiative designed to protect children from online exploitation and abuse. Led by the U.S. Attorney's Offices, Project Safe Childhood marshals federal, state, and local resources to better locate, apprehend, and prosecute individuals who exploit children via the Internet, as well as identify and rescue victims.
