On September 17, 2009, just after 3 pm, the four bodies belonging to Mark Niederbrock, Debra S. Kelley, and their daughter Emma Niederbrock were all found with Emma's friend, Melanie Wells bludgeoned to death at the Niederbrock home at 505 First Ave in Farmville Virginia. The bodies were discovered only three days after Emma, Melanie, and an online friend, Richard had all gone to a Horrorcore concert. It seemed like such a random slaying, but the shaky rationale becomes obvious upon further investigation.
