Crime scene photos of four of Herbert Mullin’s victims. On February 6, 1973, the four teenager boys, David Allan Olliker, Robert Michael Spector, Brian Scott Card and Mark John Dreibelbis, decided to set up a tent an go camping in the woods. Mullin had been walking around in the area before making his way to the boys. He had been having a normal conversation with the teenagers, but claimed to be a park ranger after a while. He shout at the boys and ordered them to leave the woods due to pollution, but eventually ended up in shooting the four. The bodies were discovered one week later.
