The body found Thursday has not been identified, but a medical examiner was at the scene. Authorities had suspected they might find the remains of Abraham Shakespeare, who was last seen in April.
The house is owned by the boyfriend of Dorice Moore, who authorities have called a "person of interest."
Moore has said she doesn't know where Shakespeare is, but authorities say she transferred more than $1 million from his bank account into hers. She said the money was a gift. No charges have been filed.
Shakespeare won $31 million in 2006.
