A Cobb County teenager has been sentenced to life plus 30 years in prison after sexual offenses involving a 16-year-old girl and an 18-year-old woman, prosecutors said.

Rome DaQuie McDowell, 17, entered the victims’ bedrooms on consecutive days last December and committed the crimes, Cobb County District Attorney spokeswoman Kim Isaza said.

Both victims’ family members were home during the incidents, Isaza said. Neither victim knew McDowell.

McDowell fled both crime scenes after the victims screamed, Isaza said. He has been in custody since his arrest Dec. 27.

He pleaded guilty to rape, aggravated sodomy, false imprisonment, burglary, sexual battery and theft, Isaza said.

Assistant District Attorney Lindsay Gardner, who prosecuted the case, said McDowell “is the definition of a predator, lurking in the night, preying on teenagers who are asleep in their beds.”
