Hide ya kids for real… Two teen girls preyed on an autistic kid, forcing him to walk across a frozen pond at knifepoint and perform a sex act with a pet.

According to NY Daily News reports:

Lauren Bush, 17, and her 15-year-old accomplice were arrested by the St. Mary’s County Sheriff’s Department. Sheriff Tim Cameron told the Daily News Wednesday the “heinous” allegations in this case are some of the worst he has ever seen and has shocked the rural Maryland county.

The suspects recorded themselves assaulting their 16-year-old mentally challenged victim by pointing a knife to his throat, making him walk across a frozen pond and not helping when he fell in multiple times and kicking him in the groin, Cameron said.

Perhaps the most appalling charge was a sexual act they allegedly coerced him into performing.

“The victim was forced to masturbate and then copulate with a family pet,” he said. “It’s beyond comprehension.”

These acts occurred between December and March, he said, adding the girls knew the victim in the rural Mechanicsville, Md., town.The victim did sustain some injuries from the suspects’ torture, Cameron said, but he did not know the extent of it.

The suspects were arrested after the mother one of the suspects found the video on her daughter’s phone and alerted the school resource officer at the Chopticon High School where they both attended, Cameron said.

The girls admitted to filming the acts but have not said what their motivation was, he said. They were charged with assault, soliciting a subject in the production of child pornography, and false imprisonment, Cameron said adding more charges may be filed.

Bush will be charged as an adult and the other suspect will be charged as a juvenile, Cameron said. Bush has been released but the 15-year-old is still at a juvenile detention facility, he said.
