Details of the Port St. Lucie Police Investigation
The Port St. Lucie Police Department Internet Crimes Against Children Unit led the investigation that resulted in the arrest of Dr. William J. Murdoch, 45, a family medicine physician from Michigan. Authorities say the operation began in June 2025, in partnership with Homeland Security.
According to police, Murdoch communicated online with a person he believed was the mother of a 5-year-old girl. In reality, he was interacting with a detective posing as a 36-year-old woman from Port St. Lucie.
How the Undercover Operation Unfolded
Investigators created an online profile designed to attract individuals seeking to exploit children. Murdoch, using a false name, initiated contact and joined a group chat focused on child sexual abuse. He asked the undercover detective about the ages of her daughters and questioned if she was a “bad mom” or “open minded.”
Police Chief Leo Niemczyk stated that Murdoch’s messages were “extremely explicit” and indicated a willingness to travel to Florida to meet the child and become a “father figure.” The affidavit notes that Murdoch claimed to have fantasized about such scenarios for years, but said he had never acted on them before. This case is just one example of the ongoing efforts by authorities, as seen in a recent Port St. Lucie man arrested for soliciting a sexual relationship with a child.
Collaboration with Federal Authorities
The investigation involved close cooperation between Port St. Lucie police and Homeland Security. The agencies monitored Murdoch’s online activity and gathered evidence of his intentions and communications.
Authorities also discovered messages between Murdoch and other users discussing topics related to conception and abortion, further raising concerns about his behavior online.
Arrest and Charges Against the Michigan Doctor
On Tuesday, Murdoch was taken into custody by the United States Marshals Service Fugitive Task Force at ProMedica Monroe Regional Hospital in Monroe, Michigan, where he was employed. He is expected to be extradited to Florida to face charges. The ICAC investigation that led to the Michigan doctor’s arrest highlights the effectiveness of interagency collaboration in these types of cases.
Murdoch is charged with obscene communication—specifically, using a computer to solicit a parent or guardian to consent to sexual conduct involving a child. The charge stems from his online interactions and the explicit nature of his requests.
Statements from Law Enforcement
Chief Niemczyk emphasized the seriousness of the case, stating, “I’m afraid we’re just scratching the surface of what’s going on out there.” He noted that while Murdoch claimed he had not yet acted on his fantasies, investigators are working to determine if there are additional victims.
The police chief also highlighted the proactive approach of the Internet Crimes Against Children Unit, which uses undercover profiles to identify and apprehend individuals seeking to exploit minors online.
