Krystle Villanueva (born 1992) is a woman from Kyle, Texas known for mutilating her daughter, and holding back laughter during her snapped mugshot.

Krystle Villanueva is a native of Texas, born and raised. She graduated high school in 2010. She attended the Del Valle Opportunity Center, a public school in her hometown of Del Valle, Texas, after graduation.

Vilanueva has suffered from drug addiction problems and substance abuse of Marijuana, Crack, and Meth. She was later diagnosed with Bipolar disorder, Schizophrenia, and ADHD.

At approximately 11 a.m. on January 5th, 2017, Villanueva's father in law, Eustorgio Arellano-Uresti, arrived home to make himself some lunch.

As he went into the kitchen and began his preparations, Vilanueva entered the kitchen and grabbed a knife.

Which she took back to her bedroom, which is then when Arellano-Uresti heard the cries of a child.

In the bedroom, Vilanueva was stabbing her 5 year-old daughter, Giovanna Larae Hernandez.

Villanueva then went back into the kitchen and proceeded to stab Arellano-Uresti in his back and forearm.

Arrellano-Uresti ran outside where he was chased by Villlanueva with an unloaded shotgun. Neighbors in the area witnessed as Arellano-Uresti ran outside with Villanueva, not far behind, attempting to continue the assault. Villanueva had been living with Arellano Uresti for approximately one week

Villanueva returned back into the home where this heinous crime was committed.

The SWAT team was called, along with several local police officers, to the home. When they arrived they found Villanueva finishing a shower, and witnessed her daughter stabbed to death in the bedroom. Villanueva was detained and removed from the home.

Due to the amount of violence that was documented from statements provided by her father in law, neighbors, and affidavit of police officers, the Sheriff has stated that it's one of the worst cases he has ever seen.

A spokesperson with the Texas Department of Family and Protective Services confirmed that the family had previously been investigated by the agency, but did not give any specifics or the outcome of their investigation. They are, however, currently working with law enforcement.

Her friends and family were devastated and have stated that this occurred due to her addiction to drugs.

Villanueva has been charged with aggravated assault and capital murder, and now she faces life in prison or possible death penalty. Villanueva is being held on a $1.1 million bond at the Hays County Jail. Of the total $800,000 is for capital murder and $300,000 is for aggravated assault.
