A Port St. Lucie man is accused of stalking after allegedly using TikTok to expose multiple users’ private digital information. The St. Lucie County Sheriff’s Office (SLCSO) Targeted Violence Unit conducted the investigation, which led to an arrest on April 15, 2026. This incident follows other recent cases involving social media and security concerns in the area, such as the Port St. Lucie Police arrest of a 14-year-old for a Southport Middle School bomb threat on TikTok.
How the TikTok Investigation Began
A detective with the SLCSO Targeted Violence Unit began the investigation on April 10 after reviewing a 5-minute TikTok video posted to an account identified as Mark Asnea’s. In the video, 35-year-old Asea allegedly discussed having access to sensitive personal data, passwords, online purchases, device identifiers, and location information of a TikTok user he was targeting.
The affidavit states that Asea stated the user’s password, IMEI number, MAC address, and banking activity in the video while suggesting he could track a person’s movements using digital tools. The growing influence of social media platforms on local privacy and safety has been the subject of recent analysis, as highlighted in a report examining the impact of Instagram on the Port St. Lucie community.
Additional TikTok Posts Reviewed
Additional TikTok posts reviewed as part of the investigation showed Asea appearing to discuss cybersecurity tools and equipment. Investigators determined these posts raised concerns about possible unauthorized access to electronic devices.
Investigators also spoke with the individuals mentioned in the posts. Those who told police they had not authorized access to their devices or accounts were concerned about how their private information may have been obtained.
Charges and Arrest Details
Based on the findings, investigators determined there was probable cause that Asea violated Florida law related to unauthorized access of a computer or electronic device and stalking. Asea was arrested on April 15. In a separate matter, questions about public figures and their residency have also drawn scrutiny in the area, as seen in the recent investigation into a St. Lucie County Commissioner over residency claims.
He faces the following charges:
- Two counts of unauthorized access to a computer or electronic device
- One count of stalking
Pretrial Restrictions Recommended
Detectives noted in the affidavit that, given the suspect’s alleged technical knowledge, they are recommending pretrial conditions restricting access to electronic devices. The investigation remains ongoing.
