During development, there was another Special Infected called the Screamer, when attacked or agitated, the Screamer would run to a safe location and yell out a loud Scream, calling out a horde of zombies. While it was cut, many things were retained from it. The idea of attracting hordes was given to the Boomer in the form of his Bile. The concept of having to avoid an enemy completely or suffer the consequences was given to the Witch. His scream was given to the Hunter, and his maniacal cackle was given to the Jockey.
