1x19 Provenance

After a young couple is found brutally murdered in upstate New York within a locked house, the brothers investigate, and learn from their father's journal that similar deaths have occurred in the area over the past few decades. All of the couple's belongings were taken to an auction house, so they check to see if a spirit may have attached itself to an object. After asking Sarah (Taylor Cole), the daughter of the auction house's owner out on a date, Sam is able to get copies of the provenances of the items. Dean discovers that a painted portrait from 1910 of the Isaiah Merchant family had belonged to all of the other murder victims, and that Merchant had killed his entire family and then himself. Realizing that the painting is haunted, the brothers burn it, but it later repairs itself. Dean tracks down Merchant's body and cremates it, but when Sam and Sarah attempt to destroy the painting again, Merchant's daughter emerges from it, having been the true killer all along. Dean finds an antique doll with the girl's hair in the mausoleum, and the spirit disappears after he burns it. Afterward, the painting is finally destroyed and the brothers leave town, but not before Sam kisses Sarah goodbye.
