The incident is believed to have happened between 8 p.m. and 9 p.m. Apr. 14 at a house on Good Hope Road, just outside the town of Lake.
At the time investigators say the woman in her twenties was home with her infant child when three suspects kicked in her door.
"It was not just a random act. The house was chosen for a reason," said Scott County Sheriff Mike Lee.
According to Lee, the suspects were there to rob someone who apparently lived in the house in the past and may have dealt in drugs.
Lee said the woman told the suspects she did not know the person they were looking for, but they still kidnapped her and her baby at gunpoint and took them to a residence in a nearby community. Lee said at least two of the suspects raped her. In an attempt to cover up the evidence, he says they forced the victim to cleanse with water and vinegar.
"And from there it seems that they got some numbers from her telephone to call," said the sheriff. "They called and asked for ransom. Ransom was paid and she was released."
Initially, Sheriff Lee said the suspects requested $2,000 for ransom but in the end accepted $500. After getting the money he says the suspects left the woman and her baby on the side of a road outside Lake. The baby was not harmed.
The three suspects face charges for capital rape, kidnapping and extortion.
"It was not gang related as far as any initiations," said Lee. "This is not a random act where they were just looking to do something such as this. Again, it was intended, even though the victim had nothing to do with what they went there asking for."
Within twelve hours of the incident, deputies made the first arrest. 18-year-old Damion Pace of Forest and Devontae Hughes, 17, of Lake, are charged with committing the crimes. Bond was denied for both suspects.
The search continues for a third suspect, whose name was not released by authorities.
