It started as a Bible study group that later fell into spiritualism and ultimately murder. Sharon Halstead pleaded guilty in the murder of Lynn Greene. She also shot Lynn's husband David Greene, and their 3-year old son Nathaniel. Sharon believed an angel from heaven told her to "destroy" the Greene family. The Halstead murder case is presented with other true accounts about supernatural beings manifesting as angels from heaven, spirits of the dead, ascended masters and aliens.
