A man from O’Fallon, Missouri has admitted to engaging in sexual activities with a 15-year-old he met online and discussing child sex with another 15-year-old victim. Andrew Haller, aged 34, pleaded guilty in the U.S. District Court in St. Louis to two counts of coercion and enticement of a minor, one count of distribution of child pornography, and one count of receipt of child pornography.
Haller acknowledged meeting two 15-year-old girls on Tumblr before shifting their conversations to Telegram, an encrypted messaging app. The California victim reported that Haller introduced the concept of “daddy dom” and mentioned sexually abusing another teen. He imposed rules on her such as seeking permission to urinate once daily and referring to him as “Sir,” “Dad,” or “Daddy.” He also requested nude photos from her and sent images and videos involving the other victim.
Following a court-approved search at Haller’s residence in November 2023, the FBI identified the second victim who confirmed sending explicit photos at his direction. They met twice in person during 2023 for sexual activities where Haller reportedly struck her during their first encounter while taking pictures and videos. He expressed interest in abusing children too young to remember.
Haller was found possessing 195 images and 92 videos depicting known or suspected child sexual abuse material which he distributed via Telegram and Signal.
His sentencing is scheduled for January 28, 2025. The coercion charge mandates a minimum sentence of ten years imprisonment while each child pornography charge carries a five-year mandatory minimum sentence. Assistant U.S. Attorney Michael Hayes has agreed not to seek more than a 25-year prison term as part of the plea agreement.
The case was investigated by the FBI with prosecution led by Assistant U.S. Attorney Michael Hayes under Project Safe Childhood—a Department of Justice initiative targeting child exploitation launched in May 2006.
