Carl Hammer, an 81-year-old retired chemist formerly employed by the National Institutes of Health (NIH), has pleaded guilty to charges related to live-streamed sexual abuse of children. The case highlights a growing trend in the exploitation of impoverished minors overseas via online video platforms.
Hammer, who retired in 2017 after a distinguished scientific career with over 75 publications and management of a mass spectrometry facility, used a desktop computer from his home in suburban Maryland to direct the production of personalized sexual abuse material. Court documents reveal investigators obtained phone records, interviews, and a live-stream recording in which Hammer communicated with a girl estimated to be between 8 and 11 years old. During the exchange, Hammer instructed the child to reposition her camera while she engaged in sexualized dancing. In one message, he wrote, "U look so grown up."
He is scheduled for sentencing in Montgomery County Circuit Court on December 4 and faces up to four years in prison. Hammer is currently under house arrest. When contacted, he declined extensive comment but remarked, “This has been going on for too long.” His attorney, Justin Eisele, stated in court that Hammer “accepts full responsibility” for his actions and highlighted that Hammer has no prior criminal history. Eisele also noted that due to Hammer’s role as a caregiver to his ailing wife, incarceration would impose significant hardship on her.
The federal investigation into Hammer’s case began with a search of his home on December 1, 2023. Experts in child exploitation stress that such cases represent just a small fraction of the broader problem. John Tanagho, executive director of the Center to End Online Sexual Exploitation of Children at the International Justice Mission, emphasized the widespread nature of the crime, noting, “The cases we know about aren’t the tip of the iceberg, they’re the tip of the tip of the iceberg.”
The growth in live-streamed abuse involving overseas children has been reflected in other recent prosecutions. For instance, William Foster Alger, 76, of Hagerstown, Maryland, was sentenced last month to 11½ years in federal prison after admitting he paid a woman in Ecuador to produce videos of sexually abusing her 7-year-old daughter. Alger initially told investigators that the payments were intended to assist the family financially.
In another ongoing federal case, Joel Biermann, former mayor of University Park, Maryland, who campaigned on a “Protecting our Children” platform, faces six counts of producing child pornography. Prosecutors allege Biermann commissioned sexually explicit images of boys in the Philippines, including one where a child held a sign bearing the phrase “I love Joel.” Further accusations assert that Biermann traveled to the Philippines, where he sexually abused four prepubescent boys in a hotel room and attempted to rape them; these acts were reportedly recorded. Biermann has pleaded not guilty, and his attorney maintains he denies the charges. He remains in custody with no trial date set.
These cases underline the ongoing challenges law enforcement faces in combating the evolving tactics of child sexual exploitation, particularly the use of live-streaming technology to coordinate abuse across international borders.
