Mark Stephen Asea, a 36-year-old man who self-identified as a "demonologist" on TikTok, was arrested in Port St. Lucie, Florida, accused of illegally accessing the devices of two women and exposing their private information on social media, according to reports by NBC Miami and Telemundo 51.
Mark Stephen Asea built a social media identity that was as striking as it was unsettling: his TikTok profile described him as a "demonologist," "clairvoyant," "empath," "grey hat hacker," and "man of the woods."
In earlier versions of his biography, he was also described as "ex-satanist" and "cybersecurity engineer," according to investigation documents.
His police photograph—featuring black geometric tattoos covering almost his entire face and neck—went viral following the news of his arrest.
Asea's TikTok account, with over 2,600 followers, was deactivated by the platform once investigators identified the videos related to the case.
How the accused would have operated
Both alleged victims approached Asea seeking technological assistance, and it was precisely that trust that, according to investigators, he would have exploited.
In one of the cases, the woman allowed him to remotely access her computer in October 2025 to resolve an issue with an application; months later, Asea allegedly confessed to her that he took advantage of that access to secretly install malicious software.
"Briefly, the victim stepped away from the computer to go to the bathroom, and at that moment, he was able to introduce a virus, gaining access to personal information, whether it be messages or personal photographs."
A private photograph that the second victim had received via Telegram ended up appearing in one of Asea's TikTok videos, who claimed it came from WhatsApp.
The woman showed the investigators a screenshot that, according to the file, proved the opposite.
More than 100 videos and GPS tracking
The researchers documented over 100 TikTok videos in which Asea mentioned one of the women, even posting up to six in a single day.
In one of them, he said: "Talk to them about your real password," and then listed the last 10 online purchases of the victim —a password that had been shared in a private TikTok group to which Asea did not belong.
In another video, he boasted about having located one of the women using the GPS on her phone: "Thanks to the GPS that her phone had, but what did I do?" according to the affidavit cited by Univision.
The researchers also found posts containing the license plate of one of the victims, bank information, and device identifiers, as well as a website where Asea allegedly posted a photo of that woman getting a tattoo.
At the time of the arrest, the police seized computers, phones, hard drives, USB drives, networking equipment, an iPad, a Dell laptop, and even a PlayStation 5 as evidence.
A closed and reopened case
This is not the first time Asea has faced similar charges in 2026: in April, he was arrested on two counts of computer abuse and one of harassment, accusations that were dropped in May without any available records explaining the reason.
At the same time, a woman obtained a temporary protection order against him in July, but a judge revoked it on September 8.
The criminal case was reopened on September 24 with a new serious charge of unauthorized access to computers, and six days later, Asea was arrested outside his home, where a body camera of an officer captured the moment of the arrest.
Upon being registered, he commented with apparent calmness: "I’m fine. Much better than in April, I suppose, when I last saw him."
Status of the case
Asea was admitted to the St. Lucie County jail with a bail of $35,000.
In Florida, the crime of unauthorized access to computers can be elevated from a third degree to a second degree if it was committed to execute fraud, which would involve more severe penalties.
As of the closing of this note, the charges are indictments pending trial; the next hearing is scheduled for November 19, 2026.
