The House

On March 16, 2017, a retired FBI agent named Scott Horn failed to make his usual morning wake-up call to his daughter Kelly. He was a man of rigid routines—the kind who scheduled his life like clockwork after 23 years at the Bureau. When Kelly's texts went unanswered and her calls went straight to voicemail, she asked a neighbor to request a wellness check. Officers found the house in order, but the dogs had been left inside long enough to soil the floors. Scott was gone.

That evening, Scott's son Riley arrived at the house with a friend, wearing a GoPro camera—a habit he'd developed for reasons that would become clear later. As they walked up the lawn, they heard banging and clattering from the side of the house. In the darkness, they made out a tarp. What they found sent Riley running to a neighbor's house, screaming. Scott Horn was dead in his own backyard, shot in the neck and then beaten beyond recognition with firewood.
