A suicide note buried for seven years revealed multiple murder cases.
A green girl who drowned and sank to the bottom of a lake; a top medical student who jumped from a cliff to his death due to heavy debts; a pharmaceutical factory manager who died in a car accident after his brakes failed. What seemed like an ordinary accident turned out to be a long-planned murder.
For more than ten years, the murderer hid in the darkness and lay dormant. There is no evidence, the motive of the crime is a mystery, and the police are still mired in mystery after repeated investigations.
