Jason Blossom's Killer

Jason Blossom's Killer was a previously 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.

Clifford Blossom was revealed to have been Jason's killer, and Mustang as his captor. Upon this discovery, Clifford murdered Mustang and committed suicide himself.
