Gatesville, TX (KRGV) — Angela Camacho is serving a life sentence at the Christina Melton Crain Unit in Gatesville after she pleaded guilty to the deaths of her three children in 2005.

Camacho is now 47. She and her common-law husband, John Allen Rubio, were arrested in 2003 after killing their three children in the Brownsville apartment they all lived in.

Julissa was 3, John was 14 months old, and Mary Jane was 2 months old when they were killed and beheaded. Rubio was executed for killing the children Thursday.

Camacho also faced the death penalty before she took a plea deal. She was a state witness in Rubio's first trial and conviction.

Rubio had a retrial in 2010 after an appeals court ruled Camacho's statements from his first trial were inadmissible. Channel 5 News sat down with Camacho for a jailhouse interview in 2007.

"He told me a lot of things about him and the devil, and he started telling me that they were possessed, and I believed him," Camacho said. "He told me they wanted to hurt me and my babies and him and that somebody made witchcraft to us. And I started believing everything like a little girl. I don't know why, but I started believing everything like a little girl. It was my fault, too, because I was there."

When asked if she was sorry, Camacho said yes, "for letting him do whatever he did and not defending my own babies."

She is eligible for parole on March 12, 2043.
