A Missouri woman has been charged in the death of a teenage girl, whom investigators say died while the suspect's boyfriend was raping her.

Amy Leigh Hartley faces multiple charges, including second-degree statutory sodomy and abandonment of a corpse in the death of 15-year-old Khighla Parks.

According to the News-Leader, Parks died Sept. 21, 2012 during "asphyxiation sex" with Harley's boyfriend, 48-year-old Anthony Balbirnie.

Hartley was arrested after the charges against her were filed Oct. 17, Ozarks First reports.

Recently unsealed court documents state that Hartley, 37, engaged in "deviate sexual intercourse" with the teen victim, and then helped Balbirnie dispose of the body after she died.

Hartley is also charged with endangering the welfare of a child for allowing the victim into her Buffalo, Mo., home, where methamphetamine was made and used.

Court documents outline a grim scenario at Hartley's residence. The suspect invited the victim to stay at the makeshift meth lab, and "to engage in sex with multiple partners, some of whom were known by the defendant to engage in asphyxiation sex."

After Parks died, police allege that Hartley helped dispose of her body. Balbirne allegedly weighted down the deceased victim and dumped her body in a lake, where it was found by a boater on Sept. 30, 2012, according to Ozarks First.

Balbirne is currently in jail for a parole violation. He is charged with Park's murder, and faces additional counts of statutory rape, child molestation, and abandonment of a corpse.
