Jason Blossom's Killer is an anonymous character responsible for the murder of Jason Blossom on July 11th.
Jason was thought to have drowned after an early morning boat ride with his sister Cheryl Blossom on July 4th. However, his body was discovered much later on. After an autopsy, it was soon discovered that he was shot in the head and died a week later around on July 11th. Jason was also said to have ligature marks, meaning the killer could've possibly tied him up or held him captive.
It is possible that Jason's Killer also set fire to Jason's car which was riddled with evidence.
