PHOENIX -- A valley man may be facing more than 40 felony counts ranging from prostitution to money laundering to running a criminal enterprise, according to a copy of an indictment obtained by CBS 5 News.

Marvin Dewey Morris was arrested Nov. 18 in connection with the investigation.

Police began investigating in April 2008 after learning prostitution acts may have been going on at Valley massage parlors, including the Oriental Wellness Spa in Phoenix.

Several women were also arrested in connection with the investigation. At least a couple of the women had made prostitution deals with undercover officers, according to court records.

“I think it’s scandalous… I heard there was more going on than massage,” said one man who works near one of the spas. He did not wish to be identified.

Others who worked near the parlors had similar suspicions, saying the spa catered only to men.

The court records name eight massage parlors across the Valley that may have been involved in this ring.

Morris also admitted to advertising in Los Angeles newspapers for “Asian women to work in Phoenix,” according to the court records.

At one of the spas, a worker who didn’t want to be identified told us the spa was under new management. She said during the couple of weeks she’s worked there, she’s already run into customers asking for sexual favors.

“Some would say, ‘Are you finished?’ I said, ‘Sure, we’re finished. It’s a half hour already.’ Then the men ask, ‘You don’t do something extra?’ I say, ‘Nope. Nope,’” said the worker.

Police also investigated possible human trafficking. Records show officers found clothes hanging in the closet and kitchen utensils in the cabinets, along with stockpiles of food. Investigators said those indicators pointed to possible human trafficking.

Also, Morris paid the rent at an apartment for two women. The apartment manager believed padlocks had been mounted outside the doors that could have locked the women indoors, according to the records.

CBS 5 News reached the Arizona Attorney General’s office late Tuesday. A spokesperson said she may be able to comment on the case Wednesday.

CBS 5 News was unable to reach anyone for comment at Morris’ Scottsdale home.
