A 34-year-old Norcross man gave marijuana to a 14-year-old and 15-year-old before sexually assaulting them, the Gwinnett County District Attorney’s Office said.

Ronnie Antwan Stone was convicted of rape, aggravated child molestation, statutory rape, enticing a child for indecent purposes and contributing to the delinquency of a minor on Oct. 23 after a one-day bench trial.

Two female cousins were chatting online with Stone the day after Christmas in 2016. The girls had met Stone at a Christmas gathering.

He sent a car to pick them up and bring them to his home in Norcross, the DA’s office said. When the girls got there, Stone put on a movie, gave the girls “a drink of some sort” and marijuana, according to the DA’s office. The 15-year-old cousin smoked the marijuana, but the 14-year-old cousin did not, they told police.

Stone had sex with the 15-year-old, and the girl would not wake up afterwards, the 14-year-old told police. The younger girl had seen her cousin smoke marijuana before, but never react like that, according to the DA’s office. Stone then ordered the 14-year-old into another bedroom, where he raped her, the DA’s office said.

One of the girls’ mothers contacted them early the next morning and picked them up from the home; Stone fled shortly before the mother arrived. Stone left Georgia and did not answer calls from a detective assigned to the case, the DA’s office said.

On the morning after the assault, Stone told his girlfriend, who knew the cousins’ family, that he had had consensual sex with both girls.

Gwinnett County Superior Court Judge Ronnie Batchelor sentenced Stone to life, with the first 20 years to serve in prison.

He was acquitted of one charge of aggravated sexual battery and one charge of enticing a child for indecent purposes.
