Proof of Innocence

[DISCLAIMER: THIS STORY IS NOT MINE, THIS IS AN MTL OF A CHINESE NOVEL.]

Duan Hanjiang, the captain of the criminal investigation team, went out for breakfast and came back to find someone killed in his bathroom. The deceased happened to be the fugitive suspect of a homicide case he was responsible for 8 years ago. All clues pointed to him as the murderer.
So, in the blink of an eye, he went from being the captain of the criminal investigation team to a suspect of the murder.

"When all the evidence points to you as the murderer, do you still insist that you are innocent?"
"Even if you are on the road of crime, do you have to prove your innocence?"
"This is a long road leading to darkness."

--We only stick to the bottom line for those who have lost their freedom and lives because of being wrongly accused.

A criminal genius who was just released from prison for murder, a criminal investigation policeman whose license was revoked as a suspect, a thorny journey of proof of innocence.
