As a guardian, she had full control over those people's finances, their property and nearly every aspect of their lives.

And as a guardian, Parks exploited at least 150 of those vulnerable Nevadans and "systemically bilked them out of their life savings," law enforcement officials said Wednesday.

A Clark County grand jury indicted Parks on more than 200 felony charges that include racketeering, theft, exploitation and perjury. Parks and her husband were arrested in Pennsylvania just hours after the indictment came down. It was unclear Wednesday night what agency made the arrests.

Three other people were indicted Wednesday: Parks' business partner, Mark Simmons; her husband, Gary Neal Taylor; and her former attorney, Noel Simpson Palmer. Simmons was arrested in Indiana sometime Wednesday, according to a Metropolitan Police Department press release.

But Clark County District Attorney Steve Wolfson made it clear in a press conference that Parks "was the No. 1 target in this investigation."

The 123-page indictment, which laid out the 212 felony charges levied against Parks, claimed she used her position and her company, A Private Professional Guardian, LLC, "to steal funds belonging to elderly and disabled persons over whom they had guardianship authority."
