Season 1
In Wolf's Bane Mr. Harris admits that he gave information about how to commit arson (and get away with it) to a woman he met in a bar. He believes this mysterious woman ultimately used that information to burn down Derek Hale's home and also noted the strange design of her necklace, which he had sketched for Sheriff Stilinski.

The woman is later revealed to be Kate Argent, who had gave the necklace in question to her niece Allison Argent in The Tell.

Before her death, Laura Hale was apparently trying to track down the arsonist and found Harris.
