Tinder killer who believed he was a warlock said he 'picked the wrong person' after murdering woman

Sydney Loofe thought she was heading out for a second date with a woman she met on Tinder. Instead, the 24-year-old vanished — and the man convicted of her murder would later make a disturbing admission about why she proved to be the "wrong person" to kill.

"I don't regret killing Sydney," Aubrey Trail said, according to filmmaker Christopher St. John. "I don't regret killing somebody, but I regret killing ... I picked the wrong person."

Trail, then a 52-year-old con man, was convicted of strangling the Nebraska store clerk with an electrical cord in 2017, cutting her body into 14 pieces, placing the remains in garbage bags and dumping them in roadside ditches. At the trial, witnesses testified that Trail and his girlfriend, Bailey Boswell, then 25, had solicited them for group sex and talked about the occult and gaining "powers" through killing.

"One of said that the culprits were in a frenzy," St. John told Fox News Digital. "They were looking to do this, and Sydney was the available target. She was trusting and innocent and fit the profile. You then later hear Aubrey Trail, the murderer, says, 'I picked the wrong person.'"

"I think that's incredibly chilling for me because he has no remorse, but he wishes that he hadn't chosen someone with such strong family and friends because it led to his capture."

Loofe's murder at the hands of Trail, who described himself as a "powerful warlock" and the leader of a sex cult, is explored in the new Hulu "Swipe Right on the Devil." The three-part series features interviews with Loofe's loved ones and investigators, as well as recordings of Trail from death row.

Loofe, a cashier at Menards, a home improvement store, lived alone in an apartment with her cat, Mimsy. According to friends, she was yearning for a relationship. On Tinder, she came across a profile for a woman named Audrey, an alias used by Boswell. After matching and exchanging messages, the two women went on their first date. They planned a second date for the next day. Loofe was smitten.

"Sydney was like any one of us," said St. John. "She was feeling lonely and searching for belonging. She had gone on a date with this woman, and she was so excited that she immediately wrote to her friends. They were like, 'Great, nothing to worry about.' And she was never heard from again. Something awful came out of the darkness."

When Loofe didn't show up for her morning shift the following day, her family requested a welfare check. Police found her car in the driveway. Her work clothes and purse were laid out for work. Her cat hadn't been fed.

Loofe's friend, Brooklyn McCrystal, knew that she had been on a date the night before she disappeared. McCrystal created a Tinder profile to find Audrey in hopes of getting her contact information. When McCrystal matched with Audrey on the dating app, they exchanged phone numbers. McCrystal gave Boswell's information to police. Loofe's friends also showed investigators her final social media post, a selfie shared on Snapchat captioned "Ready for my date."

"Brooklyn provided the first big break in the case," said St. John. "She catfished the bad guys. There's digital tracking. It's got all the hallmarks of an amazing investigation. But ultimately, what led to Aubrey and Bailey's capture was the people who were devoted to Sydney searching for answers."

Boswell refused to cooperate with investigators. When police tracked her phone, they learned it was a burner phone registered under a fake name. They traced the phone to hotels in the area,
