A teenage girl impregnated during a rape by a relative was beaten by four family members to induce an abortion, Dallas police say.
The affidavit said family members discovered the girl was pregnant and she was given multiple doses of birth control pills, emergency conception pills and cinnamon tablets by one of the suspects in an attempt to abort the baby.
The girl told police that because that didn't work, the suspects beat her for six hours and she ended up giving birth to a stillborn child.
The family then attempted to cover up the crime by burning the 8-month old stillborn baby on a charcoal grill at a home in Pleasant Grove in Dallas, according to police.
Two days later, one of the beating suspects paid another $25 to "take care of the rest of it," documents said, and the remains were disposed of in a plastic bag at an unknown location.
Police are searching for the remains.
Police said the sexual assault occurred in August 2012. She was beaten months later in 2013. An affidavit said the hours-long beating wasn't reported until May 22, 2015 when a woman who said she witnessed the assault took the teenager, now 16, to police.
The woman who helped file the police report told authorities the girl was crying in extreme pain during the beating. The affidavit said one of the suspects told the girl to "shut up" and cry into a pillow during the assault.
Officers arrested 27-year-old Cedric Jones, 45-year-old Sharon Jones, 25-year-old Cecila McDonald and 27-year-old Lonnell McDonald, and charged them with engaging in an organized criminal activity.
All four remain in the Dallas County Jail where they are being held on $150,000 bond.
Police said they also arrested 22-year-old Robert Cayald and charged him with aggravated sexual assault of a child. Cayald is being held on $25,000 bond.
Deputy Chief Gil Garza said more charges are possible as the investigation continues.
"There is still a lot of work to do," Garza said.
The teenager, now 16, is in the custody of Texas Child Protective Services.
CPS spokeswoman Marissa Gonzales said six other children at the home -- a 15-year-old brother, 14-year-old sister and four children belonging to a beating suspect -- were taken into custody Tuesday.
