FLORENCE — A woman accused of killing her boyfriend in an Apache Junction Walmart parking lot a year ago has accepted a plea arrangement.

Dalia Villalobos, 23, was arrested on Feb. 20, 2019, after she allegedly struck her boyfriend, Oscar Coronado, with her vehicle outside the Walmart in Apache Junction. He died later that evening at a hospital.

Villalobos pleaded guilty to manslaughter Feb. 5 in a plea agreement with state prosecutors. The charge is a Class 2 felony, punishable by a presumptive sentence of five years in prison. She could be sentenced to as much as 12.5 years.

According to a probable-cause statement written by the Apache Junction Police Department, Villalobos told investigators her relationship with the victim had been “physically and mentally abusive.”

On the night of the incident, Villalobos claimed she and Coronado got into a verbal fight and he shouted epithets at her. While in the parking lot, she claimed Coronado exited the car and started banging on the windows.

Villalobos initially told AJPD she accidentally hit Coronado with her car. She then changed her story to say she was angry at the victim for all the alleged abuse and intentionally ran him over. She alleged she only meant to “bump” Coronado and not kill him.

Villalobos also admitted to not calling 911 immediately because she was afraid of getting arrested, according to the police statement, and fled the parking lot. She claimed she went back to Walmart, where bystanders had stopped to help Coronado.

The victim was taken to a hospital and later died from his injuries. Villalobos was taken into custody and was charged with second-degree murder.

Villalobos has been held in custody at the Pinal County Adult Detention Center for nearly a year and will remain there until she is sentenced. She is scheduled to be sentenced on March 2 at 11 a.m. by Superior Court Judge Patrick Gard.
