- Appeared in: 1.03 Dead in the Water (episode)
- Dispatched: when both boys who had killed him die
- See also Ghost
Thirty-five years ago a young boy, Peter, was bullied by two other young boys, Jake Devins and Bill Carlton. One day the two boys held his head under the water in Lake Manitoc, and he drowned. Possibly prompted by the the fact that the lake will soon be drained, Peter's spirit has started to take revenge by killing those close to Jake and Bill, now grown men. Christopher Bar, Sheriff Jake Devin's son-in-law, was killed and then Bill Carlton's children, Will and Sophie. All died by being drowned - all in the lake, except Will who was drowned in the kitchen sink. Peter's spirit also tried to drown Andrea Barr, Jake's daughter, in her bath.
Sam and Dean unravel the mystery just as Peter has lured young Lucas Barr into the lake. When Jake offers his life in exchange, Dean is able to rescue Peter and Peter's spirit is put to rest.
