Undercover ICAC detective investigation by PSLPD leads to arrest of Michigan family physician for seeking and soliciting a mother to engage in sexual relations with her 5-year-old daughter.
The PSLPD’s ICAC (Internet Crimes Against Children) Unit and digital forensic experts work tirelessly to monitor the dark web and keep our community safe from predators.
An undercover ICAC detective with the PSLPD began the investigation in June 2025 when the suspect, Dr. William J. Murdoch, started chatting online with our undercover “Mom.” Murdoch sought a platonic relationship with the fictitious mother to see if she would allow her 5-year-old daughter to be courted and have sexual relations with him.
During the investigation, chilling messages were exchanged outlining his plan to manipulate the child and quickly turn the situation sexual. Murdoch detailed his deranged behavior, which is too explicit to share in full. However, he varied in engaging in sexual acts in multiple ways.
During the digital forensic analysis of Murdoch’s iCloud account and messaging, he was communicating with the undercover detective, where additional conversations were found revealing that his training as a medical professional could aid in other alarming forays into the dark web. This, again, is too explicit to share in full. However, it involves conversations about: conception, full-term abortions, and intentional consumption of drugs and alcohol to cause birth defects.
An arrest warrant was immediately issued for Murdoch on charges of soliciting parental consent for a minor’s involvement in sexual conduct.
Murdoch was arrested by U.S. Marshals and will be extradited to the state of Florida. These charges are based on evidence found during the investigation.
If you or someone you know is a victim of sexual abuse, call 911 or, to remain anonymous, call Treasure Coast Crime Stoppers at 800-273-8477.
