Brett Michael Dadig, a 31-year-old resident of Whitehall Borough, Pennsylvania, pleaded guilty on March 19 to 11 counts of cyberstalking, interstate stalking, and making interstate threats, according to United States Attorney Troy Rivetti.
The case highlights the use of technology in harassment cases that cross state lines. The charges stem from a series of incidents between May and November 2025 in which Dadig targeted multiple female victims across several states.
According to information presented in court, Dadig used his phone and the internet to harass and intimidate women with whom he had romantic interests. Several victims were employees at fitness establishments in different states. The harassment included showing up uninvited at victims' homes and workplaces, following them from their places of business, taking and posting unauthorized photos online, and sharing private details such as names and locations. His comments referenced violence including breaking jaws and fingers, dead bodies, burning down gyms, and threats about "judgment day." Two Pittsburgh victims obtained Protection from Abuse orders against him; these were violated both online and in person. When banned from businesses or reported to police in one city, Dadig would move on to another city to continue his conduct. The indictment also noted that he relied on advice from an artificial intelligence chatbot during his stalking activities.
Sentencing is scheduled for July 9. Each charge involving a Protection from Abuse order violation carries a minimum sentence of 12 months in prison. In total, Dadig faces up to 55 years in prison and fines up to $2.75 million. The actual sentence will depend on the seriousness of the offenses and any prior criminal history.
Dadig remains in federal custody pending sentencing. Assistant United States Attorneys Nicole Vasquez Schmitt and Hillary M. Weaver are prosecuting the case. The Federal Bureau of Investigation led the investigation with help from local police departments.
