A person, dressed in a black hoodie and sweatpants, creeps through the forest. He trudges through a campsite and finds a tent. He enters it, staring at the few people quietly sleeping. He grabs a knife from his pants and cleanly stabs it through their neck. He quickly leaves, his footsteps unrevealing. From his pants, he drops a single piece of paper. A note. 

At sunrise, people get up. Dr. Bob James wakes up and gets dressed. He makes himself a cup of coffee. He exits his tent, greeting his fellow campers with a friendly, ” Good Morning.” "Today is a great day. I can maybe go fishing today with Amelia and-”, he thinks but is interrupted by a scream. “ Help, Amelia and the others are- dead!”, says a camper.  People crowd around the tent, trying to get a look at the scene. People gasp at the camper, dead with stab wounds through their neck. Dr. James enters the scene, calmly telling people to call emergency services. He notes in his,” No blood around the wounds.”
