Tammy was last seen walking to Lincoln Street School in Exeter, New Hampshire on November 13, 1984. A neighbor saw her cross Court Street at approximately 8:00 a.m., but she never arrived at school. Victor George Wonyetye Jr. was named as a suspect in Tammy's case shortly after she disappeared. Wonyetye was employed at Brad's Custom Auto Body on Main Street in Exeter in 1984, which was located several blocks from where Tammy was last seen. Police found a photograph of Tammy in his house as well. He was never charged and he died in prison in 2012. Tammy remains missing and her case is unsolved.
