there was a movie a while ago on abc family, late 90s i would say, about a family who moved to a small town. the town was in the woods. they had a daughter i believe that was autistic and communicated with the children who had lived in her house previously that had been killed. she started painting through inspiration of the ghosts. Her brother was kidnapped. The girl drew pictures which led to where her brother was. It turned out that the town sheriff was a killer and had killed many children and buried them in a cave in the woods.
