Nearly 21 years ago, Andrea Yates horrified the nation when she confessed to drowning her five young children in the bathtub of their suburban Houston home on June 20, 2001.
After she drowned the children, she called 911 repeatedly and then called her husband and told him to come home from work.
Yates was charged with five counts of capital murder. Her high-profile 2002 trial made national news. It was broadcast live and even landed on the cover of PEOPLE.

But despite the fact that Yates confessed to the killings, the complex case had several twists and turns.

The prosecution pushed for the death penalty and primarily focused on the victims: Noah, 7; John, 5; Paul, 3; Luke, 2; and Mary, 6 months. But the defense contended that Yates' depression and psychosis caused her to kill her kids, and argued that she needed intensive mental health treatment rather than incarceration.

Her husband, Rusty, initially stood beside her. “She loved those kids,” Rusty said to the crowd of media in 2001. He later divorced Yates and remarried.

Since January 2007, Yates has been at Kerrville State Hospital, a mental facility in Kerrville, Texas. Although she was remanded to the mental facility more than 15 years ago, Yates can undergo a review every year to see if she is competent to leave the facility.
Now 57, Yates opts each year to waive her right to be reviewed. PEOPLE confirms that she has never undergone review, choosing instead to continue treatment. Details of her treatment have not been released.
Her defense attorney, George Parnham, keeps in contact with Yates and says that Yates is “happy” in the facility.
“She’s where she wants to be. Where she needs to be,” Parnhamtold ABC Newslast year. “And I mean, hypothetically, where would she go? What would she do?”
