Guys, i think i just discovered a new easter egg. The location is in The Old Salvatore Mansion.

 

Note: I'm not proving that the easter egg that I discovered is true. I'm just here to ask you guys if its true or its just a false. I discovered this in accident.

 

I come to the location of the mansion to get the secret location of the Sultan RS. After i get out of my vehicle, i killed some NPC's near the mansion, well, you know, for fun. And after a few seconds, I heard a man or something with a weird voice talking, but i can't understand what he says. The voice sounded very different than the voices coming from the NPC's in Liberty City. It sounded like a monster. Its impossible that the voice comes from the scared NPC because i killed some NPC, because the unique voice that i heard is not a scared voice, it seems like he is telling something. I discovered this in 2018 so i can't remember whatever he says, what I remember is he said "Grah Grrraghh" or whatever, it doesn't sounded English.

 

Is it false, or true?
