Texas police issued an arrest warrant Wednesday for millionaire artist Stanley Marsh 3, who stands accused of nearly a dozen counts of child molestation.

Special prosecutor and director of the Lubbock County district attorney’s office, Matt Powell said Marsh faces six counts of child sexual assault and five counts of sexual performance by a child that involve two alleged victims. He said he did not know whether Marsh had been taken into custody.

“This is the beginning of the process,” Powell said. “This is what we felt like we needed to do.”

Marsh lives in Amarillo, Texas, where he is best known for his Cadillac ranch, an artistic display of 10 brightly painted Cadillacs buried nose-down along a Panhandle highway, the AP reported.

Also known for his philanthropy, Marsh has been hit with several lawsuits in recent months accusing him of paying teenage boys to perform sexual acts; in at least one case he is accused of providing a boy with drugs and alcohol.

In 1996, Marsh was indicted on charges of indecency with a child, but the charges were dropped.  That same year he acknowledged no wrongdoing in a settlement with a youth who claimed he was sexually abused by Marsh.

Marsh’s attorney, Kelly Utsinger, was not available for comment.
