Hannah Webster was a mortal who was the assistant of the successful Buckland Auction House owner Rex Buckland, until the two were murdered by the two warlocks; who assumed their identities.
Her death was discovered by Inspector Andy Trudeau after Prue Halliwell asked him to do a background check on Hannah Webster and Rex Buckland. The false Hannah Webster was shortly vanquished after this discovery, along with her the fake Rex Buckland.[1]
