Criminal Minds S14E02 - Starter Home

When the mummified remains of numerous victims are found in the walls of an elderly couple's remote South Carolina home, Rossi, JJ, and Simmons are dispatched to track down a trail of clues that date back over 20 years. The hunt becomes urgent after BAU learns the killer has a specific ritual of when to strike, and like clockwork another person goes missing. Also, Rossi reconnects with his ex-wife, Krystall.
