A Port St. Lucie man who brands himself a “demonologist” and “Grey Hat Hacker” on TikTok is back in custody after St. Lucie County prosecutors revived a felony computer-access case that had been dropped months earlier.
Mark Stephen Asea, 36, was booked into the St. Lucie County Jail on Sept. 30 on a charge of offense against computer users, a felony. His bond was set at $35,000, according to sheriff’s office records.
The case has a tangled history. Asea was first arrested in April on stalking and computer-related charges, but prosecutors dropped the case in May. They reopened it Sept. 24 and filed the current charge over alleged unauthorized access to a computer or electronic device. Court records do not explain why the earlier charges were dropped or what led to the renewed prosecution.
According to a police affidavit, two women said their private information turned up in Asea’s TikTok videos, including one woman who said she had trusted him to help fix a computer problem.
Password and Purchase Claims
In one video reviewed by a detective, Asea allegedly recited details about a woman’s devices and claimed to know her recent purchases. A transcript in the affidavit quotes him saying, “Let’s talk about your actual password. How about we talk about the last 10 purchases you made online?”
The woman told investigators the password in question had been shared only inside a closed TikTok group chat that Asea was not a member of, though she suspected he may have accessed it through a fake account. She said no one in the chat had permission to share the password outside the group, and she did not know how he could have obtained her phone identification number or banking information.
A Tech-Help Request Turns Into Alleged Spying
The second woman told police her concerns began after a routine request for tech support. She said she let Asea remotely access her computer in October 2025 to fix an application problem. Months later, she said, he told her he had effectively planted a virus on her computer while she was in the bathroom, giving him the ability to view her information without her knowledge. She said she never authorized that access.
She also told investigators a photograph from a private Telegram message on her phone later appeared in one of Asea’s TikTok posts. He claimed in a comment that the image had come from a WhatsApp exchange, according to the affidavit, but the woman gave investigators a screenshot showing the photo had actually come from the private Telegram message.
Police also cited statements in which Asea appeared to brag about tracking her location through her phone, quoting him in the affidavit as saying, “Thanks to the GPS within her phone, but what did I do?”
Investigators said Asea posted more than 100 TikTok videos referencing one of the women, at times uploading as many as six videos in a single day. He also allegedly set up a website where he posted a photograph of her getting a tattoo.
Shifting Online Persona
Asea’s current TikTok biography lists “Demonologist,” “Clairsentient,” “Empath,” “PTSD,” “Grey Hat Hacker” and “Woodsman.” An earlier version of his account, documented in the April affidavit, described him instead as a “former satanist” and “cybersecurity engineer.”
Asea also faced a separate civil stalking case this summer. A woman obtained a temporary injunction against him in July, but a judge dissolved it and dismissed the case on Sept. 8.
Asea is scheduled to be arraigned on the felony computer-access charge Nov. 19.
