Antonio Botello-Arreola, 25, of Santa Rosa, California, was killed on September 1, 2017. After discovering the affair, Torres, her husband Rene Espinoza Martinez, and their son Rene Espinoza Jr. allegedly conspired to lure him to a remote stretch of Porter Creek Road in Sonoma County.

On the day of the killing Torres rode with Botello-Arreola in a Toyota Previa while Martinez and Espinoza Jr. followed. When the car stopped, Torres exited and Botello-Arreola was shot. He attempted to flee but fell into a ravine; his body was later found by the California Highway Patrol. Prosecutors described the murder as planned and carried out by the three family members.

Just before trial was set to begin on June 28, 2019, all three defendants entered no contest pleas. Rene Espinoza Jr. received 50 years to life for first-degree murder with personal use of a firearm; Maria Guadalupe Torres was sentenced to 25 years to life for first-degree murder; and Rene Espinoza Martinez received 15 years to life for second-degree murder.
