An internet cult, aliens, the impending rapture and the mysterious death of a man at the hands of his girlfriend — it’s not the plot of a 1980s science fiction movie, but a real life investigation into the recent homicide of a Pennsylvania man.

Barbara Rogers, 42, was charged with the homicide of her boyfriend, Steven Mineo, 32, Monday. Police say Rogers shot Mineo in the head at close range Saturday inside their home.

But Rogers said Mineo asked her to shoot him because he was having problems with an online cult he was involved in. Mineo was allegedly involved with the website “Sherry Shriner,” a group that preaches a “new world order” and discusses topics like the coming alien invasion of the United States.

“At this point, we are still looking into what the motive is,” Pocono Mountain Regional Police Chief Chris Wagner told WNEP-TV. “What we do know at this point is that Barbara Rogers had the gun in her hand. She placed the gun on Mr. Mineo’s forehead and pulled the trigger.”

Investigators also said they were looking into social media posts that reportedly detailed tensions between the couple. Rogers told police that she and Mineo were fighting with Sherry Shriner, the website’s founder.

“The victim believed that contrary to her appearance, Shiner was actually ‘reptilian,’” a criminal complaint obtained by People Magazine said. “The victim was undergoing a lot of stress through the problems with the cult.”

Rogers gave police multiple conflicting accounts of what occurred the day Mineo was killed, authorities said. She first told officers that Mineo offered to show her how to use a gun and placed her hands on the gun before guiding it to his forehead and pulling the trigger himself. She initially said they were standing up when it happened but later admitted Mineo was sitting on the floor.

Shriner, the website’s founder, denied she was running a cult and called herself “moral” and “ethical” in an email interview with People. She said she and Mineo met on Facebook in 2010 and that they recently got into it over his new relationship with Rogers.

“I didn’t know Barbara until Steve brought her into a private chat room we had,” Shriner told People. “[I] confronted Steve about her and told her who/what she was and he threw a complete temper tantrum. He was convinced Barbara was an answer to his prayers and the perfect Christian girl.”

Charlie Benincasa, a friend of Mineo’s, said he was shocked to learn of his death.

“He was not a depressive, negative dude. In the seven years I knew him, he never mentioned anything about suicide or killing himself,” Benincasa told People. “He believed that we would have to get right with God and our rights were being violated. Steve really believed in the Second Amendment and the right you have to bear arms. He was really big on that, 9/11 and FEMA camps. He felt that the government was going to take over.”

Another friend of Mineo’s, Kevin Wade, said the couple bailed on Shriner after realizing what they were involved in.

“They were too far out,” Wade told WNEP. “Instead of being religious, it was just a cult thing. They got rid of that.”
