This case is actually 17 years old, but what a messed up story.
Prosecutors accused Pelley, a high school senior at the time, of using a shotgun to kill his father, the Rev. Robert Pelley; stepmother, Dawn; and stepsisters, Janel, 8, and Jolene, 6, in April 1989 at their home next to the Olive Branch Church of the United Brethren in Lakeville, about 10 miles south of South Bend.
Investigators said Pelley was angry because his father had grounded him for stealing and would allow him to attend only the prom dance, causing him to miss a prom dinner, a bowling alley party and an outing the next day at an amusement park outside Chicago.
