July 21 ----/ In his fourth run-in with Maricopa County deputies within a year, rapper DMX now faces charges of theft of services and identity theft for trying to avoid paying $7,500 in medical bills from Scottsdale's Mayo Clinic in April.

DMX, whose real name is Earl Simmons, was arrested at a Phoenix mall Saturday. On Sunday he was held in isolation for his safety at the Towers Jail on a $60,000 bond, Maricopa County Sheriff Joe Arpaio said Sunday. Simmons was indicted Wednesday on the two felony charges, Arpaio said.

"He seems to have a long record and nothing ever happens. I am concerned that these judges keep letting him get out," Arpaio said. "I don't know how many times he has to be booked into jail. He keeps committing all these violations and keeps getting out and continues to violate the law. He has lived a charmed life."

In April, the 37-year-old rapper went for treatment at Scottsdale's Mayo Clinic. He stayed nine hours, racking up the $7,500 bill but provided hospital staff with a false name, "Troy Jones" and fake social security number, Arpaio said.

The rapper also gave a non-existent address in Yonkers, New York and provided false contact information, including the name of a girlfriend, "Jennifer Martinez" and a cell phone number, officials said.

During the execution of a search warrant, Simmons told deputies that someone in the "projects" will get the bill.

The arrest Saturday is the fourth time within a year that Simmons has been arrested or cited by MCSO. The recent case began as part of an earlier seven-month animal cruelty investigation that kicked off last August, Arpaio said.

After a tip to MCSO deputies found 12 malnourished dogs, three dogs buried, drugs, and a cache of weapons at Simmons' home in north Phoenix near Cave Creek in August.

MCSO's jurisdiction includes the unincorporated area of Cave Creek.

On May 6, Simmons received a photo-enforcement ticket for allegedly driving 114 mph on Loop 101 near Cactus Road.

During a search warrant on May 9, MCSO deputies also found five additional malnourished dogs along with weapons and arrested Simmons on suspicion of felony drug and misdemeanor animal cruelty charges. During that time, Simmons said he was sick and had been in the hospital the month before , Arpaio said.

About the same time, Simmons was cited by MCSO deputies after he drove recklessly while riding off-road in an ATV in a Cave Creek park. He had failed to pay a fee, provide identification, and was driving on a suspended license, Arpaio said.

In late June, Simmons was arrested in Miami on charges of attempting to purchase cocaine and marijuana from an undercover officer.

On July 2, when Simmons returned from Florida to the Valley, MCSO deputies arrested him at Sky Harbor Airport on an outstanding warrant for failure to appear in court.
