Paradise Lost (S04E14)

Rachel, Bailey, and their team travel to Yosemite National Park after a horrific crime where a mother and her two daughters were brutally murdered. While initial evidence seems to implicate a local outlaw biker played by guest star Douglas Bennett, Rachel develops an alternative suspect profile that suggests the killer may be someone with remorse and unresolved issues with siblings. Meanwhile, George's ongoing struggle with substance abuse leads to a risky situation that embarrasses both Bailey and the VCTF, coinciding with a visit from an attractive Congresswoman, portrayed by guest star Erin Gray, who takes a particular interest in Bailey. Back home, Rachel's new romance with her brother's drug counselor, played by guest star Joe Flanigan, faces some unexpected challenges.
