DALLAS, Texas — Four family members have been arrested on suspicion of beating a 14-year-old pregnant girl so viciously that she gave birth to a stillborn baby, the remains of which they tried to burn in a charcoal grill to cover up the crime, police in Dallas said.

The teenage victim was eighth months along when the hours-long attack occurred in 2013, according to an affidavit obtained by the Dallas Morning News.

The newspaper reports the girl became pregnant after she was raped by a family member and was “embarrassed” to go to police after the attack. A woman, who said she witnessed part of the assault, took the victim to police last month, according to the Dallas Morning News.

Cedric Jones, 27; Sharon Jones, 45; Cecila McDonald, 25; and Lonnell McDonald, 27, were arrested Tuesday on charges of engaging in organized criminal activity, the newspaper reports. They were being held in the Dallas County jail, each on $150,000 bail.

Jones is accused of giving the girl “multiple doses of birth control pills, Plan B [emergency contraception] pills and cinnamon tablets … to abort the baby,” police told the Dallas Morning News.

When those methods didn’t terminate the girl’s pregnancy, Cecila McDonald allegedly held the teen down while Lonnell McDonald allegedly bounced “repeatedly” on the girl’s stomach and kicked her, according to the newspaper.

After six hours of the brutal beating, the girl began to bleed heavily. She delivered a stillborn baby two hours later, the newspaper reports.

The suspects allegedly tried to burn the baby’s body in a charcoal grill, officials said. But when the body was not destroyed, Jones allegedly paid Cedric Jones $25 to “take care of the rest of it” and the child’s remains were thrown away in a plastic bag.
