It is the largest prostitution bust in Arizona history. Not only did investigators make dozens of arrest, they also seized cash, drugs and weapons.

The ring came to an end in August 2008, when investigators busted several Valley locations.

Police documents have revealed that the Johns generally paid a $375 all-inclusive rate. And if the escorts showed up late, they had to pay a fine.

According to investigators, the criminal enterprise was making bank deposits totaling $250,000 a month.

Here is a list and profile of those that pleaded guilty:

"As far as johns go, it is a crime, and we have met with city attorney and discussed what we could do in the city of Phoenix," said Sgt. Andy Hill of the Phoenix Police Department. "But, again, the whole point is -- we have to go to the place where the crime originated, and there are many different cities where crimes happened."

Later developments in the case against Nichta led to the arrest of David Elms, 38, the operator of the Erotic Review Web site, Thomas said. Elms is accused of conspiracy to commit aggravated assault in a case not related to the Desert Divas investigation. There is a warrant out for Elm's arrest. He fled after posting $150,000 bond.
