Zodiac Killer

The story of a young police officer who wants to catch the Chakrasri murderer. The story takes place in 1968, 1969, and 1974. The main suspect in this case is Arthur Leigh Allen. There are 2,500 suspects in this case, but the top two suspects are: 1. Arthur Leigh Allen and 2. Ross Sullivan. Arthur Leigh was arrested in 1974. He owned a rare Zodiac watch at the time, and his friends all said he was definitely Zodiac. Until 1980, he died, and his fingerprints were tested and found to be inconsistent. The next person, Ross Sullivan, died in 1977. He looked similar to the sketch and was a mentally ill patient. His handwriting resembles Zodiac's. He has many similarities, but the police cannot guarantee his identity, even though his brother said Ross was Zodiac. However, as of 2025, the case remains unsolved, and his true identity is unknown.

A genius and narcissistic murderer, he often sends challenging letters to the police after committing crimes, containing a code that is difficult to crack.
