Being a member of Trail’s group, she said, meant engaging in group sex and helping him swindle others out of money in the antique trade.

But it also involved something much more sinister, she said: murder.

The woman said Trail, who referred to himself as the “vampire,” eventually told her that to become one of his “witches,” she needed to kill someone “and take their last breath.” Trail added that she would gain even more “powers” if the victim was tortured for two to three hours beforehand.

In the beginning, she said, “it all sounded like it was real, very convincing.”

The woman, who left the group before Loofe was killed, nervously wrung her fingers as she testified. Under court order, cameras and recording devices were shut off when she took the stand. The same order was filed for two other young women who became part of Trail’s group who are expected to testify Tuesday.

Trail, the woman said, told her that the killing should “turn you on sexually” and asked her to think about what would do that.

She said she had group sex with Trail and Boswell — the “queen witch” — more than once at their Wilber apartment as well as during a trip to Branson, Missouri.
