MOORHEAD, Minn. - After Terry Jenstead's pain medication went missing for a second time last week, he and his wife, Ruby, suspected their in-home nursing assistant, 37-year-old Christie Prody.

When Ruby Jenstead mentioned her concerns to the Moorhead police, she said one officer asked her if she had ever checked out Prody's background.

She hadn't, because an agency that placed the nurse in the Jenstead home had handled the criminal background checks and waiver process.

The officer suggested that Jenstead search for Prody on the Internet herself.

And that's how the north Moorhead woman found out her husband's nurse of almost three months had been a girlfriend of controversial figure O.J. Simpson for 13 years.

"You could've knocked me over with a feather," Jenstead said on Tuesday about finding out.

Prody was charged Monday in Clay County District Court with allegedly stealing prescription pills on two separate occasions after the Jensteads installed a surveillance camera trained on where the medicine was kept.

In the time Prody worked in the Jenstead home, Ruby Jenstead said the woman never talked about her past or her time with Simpson and had been a dependable worker in the house.

"She was a very nice person and an excellent worker," Jenstead said. "You'd never have guessed that she led that kind of life."

A Clay County Jail official said Tuesday afternoon Prody was still in custody on $10,000 bail. Her next court appearance is set for April 20.

Prody, who has relatives in Fergus Falls, graduated from high school in St. Anthony Village in Minnesota in 1993. In 1996, she moved to Los Angeles and was waitressing when she met Simpson.

Two years before, the NFL Hall of Fame running back had been tried and acquitted of murder after the stabbing deaths of his ex-wife and her friend, though a civil jury later held Simpson liable in a wrongful death lawsuit.

In 1999, Prody and Simpson moved together to Miami, where their personal life generated many headlines, with police being called multiple times to their $1.1 million home. A 2008 visit by Simpson to the Fargo area - before the pair split - drew public attention, as well.

Simpson is now serving a 33-year prison term on convictions for kidnapping, robbery and other offenses related to a 2007 hotel-room confrontation in Las Vegas with sports memorabilia collectors.

In 2009, Prody told "Good Morning America" that she believed he had committed the 1994 murders, and that she feared for her life while living with him.

Later that year, Prody's brother, Barrett Prody of Fergus Falls, created a nonprofit and website to raise money for Simpson to appeal his conviction.

Barrett Prody said in a 2009 interview that his sister, then separated from Simpson and living in Fergus Falls, had nothing to do with the fundraising effort.

Calls to a number listed under Barrett Prody went unanswered.
