Seventeen-year-old Brittanee Drexel vanished into thin-air while in Myrtle Beach in 2009, where she had gone for spring break without her parents’ permission. Surveillance video from a hotel lobby was the last known visual clue to the teen’s whereabouts. Investigators traced the girl’s cell signal to a tower near McClellanville, in Georgetown County, South Carolina.

Seven years went by with no new information released, until FBI Agent Gerrick Munoz testified in federal court that a jailhouse informant, Taquan Brown, had come forward and was making allegations against, among others, a local South Carolina man named Timothy Da’Shaun Taylor. Munoz’ testified during an unrelated bond hearing for Da’Shaun Taylor in connection with a 2011 robbery.

In the video above, watch Dr. Phil’s exclusive interview with Brittanee’s mother, Dawn Drexel. Dawn relates what she says the FBI agent told her about what Brown claims he saw at a “stash house” in McClellanville, about 50 miles south of where Brittanee was last seen.

“He had said that Da’Shaun – and there were other men – that were raping my daughter,” states Dawn.
“Brittanee tried to escape,” Dawn continues. “Supposedly they ran out and got her. They brought her back into the house. They pistol-whipped her, and then they shot her.”

Dawn says the FBI agent then told her the informant claims Brittanee was killed, and her body may have been dumped in a nearby alligator pit. “My heart just broke, because Brittanee didn’t deserve this,” says Dawn.

Brittany nor her remains have ever been found.
