Brynn Walker was a top equestrian before she was found dead in the woods. A jittery meth-head was caught going through her pockets at the crime scene. This could be a drug-related beating. Traces of glitter are found on the victim's lips and a bloody handprint was found on her shirt. It belongs to an ex-addict named Zoe Brant, who is currently in prison. Megan asks, "How do you kill someone if you're already behind bars?" Excellent question!

Zoe Brant (guest star Crystal Bowersox of American Idol fame) took part in Brynn Walker's horse therapy for prisoners program. She claims the blood came from a cut she sustained after a horse kicked her to the ground. Brynn helped her up. Bud thinks Zoe is an addict who killed Brynn during an escape attempt. Megan disagrees. After all, Zoe has a daughter she loves and only three months left on her sentence. She believes people can change.

A spiral fracture on Brynn's leg suggests she was dragged by a horse after getting her foot caught in her stirrup. Will Brooks manages the stables where the victim used to ride. He says Brynn only ever rode one horse, but that wasn't the one she fell from. Peter and Ethan find a white mystery steed in the woods. Megan seeks some assistance from her daughter, Lacey, who notices that the safety stirrup on the white horse is broken. Someone tampered with it.
