After hearing Colleen and Chelsea's story, the detectives go their separate ways in search of evidence. Randall interviews Dr. Ophelia Garmon-Brown, a family physician who has spent the last 20 years researching the connection between medicine and faith.

"The more I understand about science, the more I lean towards that there has to be a power greater than ourselves to bring all of this together the way it is," she says.

Randall is pleased after his conversation with Dr. Garmon-Brown. "She does have one foot in each world and doesn't feel torn," he says. "She has a foot in the world of science. She's an eminent physician. She's the head of the County Medical Association. And she's also a woman of deep faith."
