The next noteworthy tip came from an anonymous caller who said Keyes had a sister in Smyrna, Maine, who belonged to the Amish community. This caller also said that when Keyes was a young man, his sister and parents lived in Idaho with a Christian identity group that preached white supremacy. Two other tips had to do with Heidi’s church. The first caller was from Wells, Texas, who said the town had recently been taken over by a cult. Israel Keyes, the tipster said, was a member.
