A self-proclaimed Pittsburgh social media influencer was indicted for the "relentless" stalking and harassment of nearly a dozen women across multiple states, federal prosecutors announced on Tuesday.

Brett Michael Dadig, 31, would meet women in gyms and stalk them, moving around to a different city whenever he was banned or reported to police, First Assistant U.S. Attorney Troy Rivetti said in a news release. He allegedly documented his desire to find a wife and his interactions with women on his social media accounts and podcasts. 

According to the indictment, Dadig took advice from an artificial intelligence chatbot and tried to meet women at gyms. He said ChatGPT told him that God's plan for him was to build a platform and stand out. 

He's accused of harassing, intimidating and threatening them through social media posts and phone calls. Prosecutors said he would show up at their homes and workplaces and follow them, try to get them fired and post pictures of them online. 

"Some of Dadig's threats and online content included references to breaking his victims' jaws and fingers, dead bodies, burning down gyms, strangling people, being 'God's assassin,' and his victims rotting in hell and suffering 'judgment day,'" the U.S. attorney's office wrote in a press release. 

Over the summer, Dadig was accused of going to multiple gyms in the South Hills area, leading to a warning post from one fitness center. In August, Bethel Park police arrested and charged him for violating a protection from abuse order.

"I just want to apologize if I made anyone feel uncomfortable at F45, at Flo Yoga, at Stride," he said in a social media afterward.

Prosecutors said Dadig also violated another PFA against him.  

A federal grand jury indicted him on charges of cyberstalking, interstate stalking and interstate threats for allegedly harassing 11 women from Pennsylvania, Ohio, Florida, Iowa and New York.

"As charged in the Indictment, Dadig stalked and harassed more than 10 women by weaponizing modern technology and crossing state lines, and through a relentless course of conduct, he caused his victims to fear for their safety and suffer substantial emotional distress," Rivetti said in a press release. 

"We remain committed to working with our law enforcement partners to protect our communities from menacing individuals such as Dadig," he added. 

He faces a maximum total sentence of up to 70 years in prison, a fine of up to $3.5 million or both. He's been in custody pending a detention hearing that's now scheduled for Dec. 15.
