Three boys have been accused of gang-raping a 13-year-old girl who snuck out of the house with her older sister to meet them, according to authorities.

Cequez Jones, 17, of Augusta, and two juveniles, ages 15 and 14, have each been charged with aggravated child molestation in last Thursday’s incident.

The victim’s foster mother reported the crime. She said her two foster daughters, ages 13 and 15, took her car without permission in the middle of the night Thursday. At 4 a.m. Thursday, they went to “meet boys they met and only knew from Facebook,” a sheriff’s report says.

The victim told her foster mother that the three teens “took turns forcing their penis into her vagina after pulling her into a white Honda” against her will, the report says. It took place in front of a Blanchard Road residence.

“All of the males had black handguns which they attempted to insert into her vagina,” a report says.

One suspect tried to perform anal sex, which prompted the girl to try and jump away. But another grabbed her hair and forced her to perform oral sex on him, the report says.

The victim’s older sister stayed in their foster’s mother’s vehicle and told deputies she thought the sex was consensual between her sister and the teens, according to a report.

Patrolling deputies drove by, prompting the three suspects to run out of the white Honda and leave the girl. Deputies transported the victim back home, where the girl confessed to her foster mother what had happened. She took the girl to Doctors Hospital for a rape kit.

Rape Crisis and DFACS officials were notified.
