Armed 'ninja' sister-wives caught trying to abduct Utah sex assault victim

The family of a 15-year-old witness in a Utah rape trial were shocked to find two of the defendant's "wives" in their house late Thursday night dressed like "ninjas" and armed with knives and stun guns.

According to Salt Lake City's Fox 13 News, a male relative of the 15-year-old girl -- who is set to testify that she was sexually assaulted by the man on trial -- heard a noise downstairs in their house late at night.

“I heard a creak, and there was silence for about 30 seconds,” said the man, who declined to be identified in order to protect the 15-year-old's identity.

The home invasion took place during a violent thunderstorm, at first making the man believe that what he heard was normal noise from the storm. Sensing something was wrong, however, he went to the stairs.

“I went to the bottom of the stairs and saw a couple of ninjas coming down,” he recounted. “They were all dark gray or black, and they had black rubber gloves on and masks. All I could see was their eyes.”

“My adrenaline was pumping so bad” when he encountered the two dark figures, the man said, that he was heedless of the stun guns and knives they carried. “They grabbed for me and one of them covered my mouth, and the other grabbed my throat, but they were both pretty small so I threw them back and started shouting to get anybody awake that I could.”

The family believes that the two women intended to abduct and possibly kill the 15-year-old witness. Both attackers are currently behind bars, although police have declined to release their names in the interest of preserving the anonymity of the witness.

“The witness that will be testifying is a juvenile,” said Officer Craig Powell of the West Jordan Police Department to Channel 13. "“We do believe [the home invasion] does involve the testimony that would be given in court next week.”

Two two "ninjas," the witness' family said, are in a polygamous relationship with the alleged rapist.

"I knew exactly who I was dealing with," said the male relative who caught the women.

“It was so surreal,” he said. “I wasn’t processing what was fully happening. I was just working on instinct. All of us are still floored by it.”
