These characters were campers at Camp Arawak. They threw sand at Angela Baker and her cousin Ricky Thomas. She (He at the time) gets revenge on them by killing them by hatcheting them. Their bodies were found by Eddie (and when he called Ronnie, mistakenly said "3 of them?", but in actuality, it was 4, not 3). There were actually 5 campers that threw sand at Ricky and Peter, but one of them didn't die because she, another camper (Who didn't throw sand at Angela and Ricky) and Eddie left so Eddie could take them back. They are Angela Baker's 5th, 6th, 7th, and 8th victims.
Cause of death: Hatcheted numerous times by Angela Baker
Angela Baker's motive for killing them: Throwing sand at her and Ricky
