What is this TV movie?

I’m looking for a TV movie that I saw on either Lifetime/Hallmark channel between the years of 1995-2001. It was about a teenage boy who goes to stay with his aunts for the summer. One of his aunts has a mental disability and cannot speak. It is revealed that this disability was caused by being drowned and almost murdered as a child because she saw her attacker either hang or burn her black friend to death. The teenager finds drawings of his aunt’s friend being hung or burnt in the attic. The attacker is present in another one of the sister’s lives and tries to kill the woman again later in the movie. Please help me, I’ve been searching for this movie for 15 years!
