Friday the 13th

The grisly discovery of human bones in a ravine re-opens a 15-year-old missing persons case, and Swarek teams up with his old training officer, Charlie Walsh, in an effort to close the case. But an up-close-and-personal look at Charlie's life makes Swarek think twice about whether he wants to continue in his mentor's footsteps. And a weird night gets even stranger when Chloe and Dov can't agree with how to deal with a witch and her disgruntled client.
