Zachary Penna was having a horrible day. He left work early to pick up his car but the auto shop said it wasn’t ready which ruined his evening plans. He had to walk home in the South Florida heat and when he got there he was locked out. It’s enough to piss anyone off but Zachary had a different reaction. He stripped off most of his clothes, trudged through some nearby woods, and murdered Freddy Sanchez and Wayne Dixon, two complete strangers, in their own home.
