The myth originated on the GTA Myth Wiki forums when a Russian user named Voldemar543 posted a story about the ghost. The original sighting was written in Russian, but fans translated it into English:
|“||One day I was walking around Ocean drive and shooting at street criminals. It was about 2 o'clock in the morning. Suddenly I heard a strange noise, similar to the blow of a cleaver. At the same time, a faint rustle was heard... Two seconds later, on the wall of the building, I saw a shadow, similar to a cook. A few seconds later the shadow disappeared. The next day I found nothing on Ocean Drive. I think that the shadow and the noise is the case of the ghost of Leo Teal. The version of the game is Android.||”|
Upon technically analyzing the claim, at first, it may seem possible that the investigator's claim is true, but it was a misconception. The investigator possibly sighted the strange face textures in alleys in Washington Beach, and the myth could be a mistake, but his succeeding claim that the shadow just vanished could be a lie or myth-making strategy, as shadows aren't programmed to be in the game. Another scenario could be that the version the player was using could be a modded one. All in all, the myth itself is highly unlikely.
