TUCSON - Joshua Hilaire pleaded guilty on Feb. 6, to an amended count of second-degree murder and domestic violence for killing his ex-girlfriend, Rosaura Hernandez, on May 6, 2018.

Tucson Police Department entered Hilaire's east side apartment and found Hernandez dead on the kitchen floor.

Hernandez's mother, April Barbosa, said she was in bed for months after her daughter's death and even dropped down to 90 pounds.

When the court summons for Hilaire's plea arrived at their home, all those emotions came back to her.

"When you get there and you know 'Okay I'm gonna see him,' and you tell yourself 'I'm gonna be okay, I'm gonna be okay.' There is no okay, there is no okay with being in the same room as… as the person that killed your child," said Barbosa.

In May 2018, Hernandez went to Hilaire's apartment to pick up her stuff after the couple broke up the day before. It wasn't until later that night that Hernandez was found stabbed and strangled in the apartment.

Last week, Hilaire pleaded guilty and is facing between 16 to 25 years behind bars.

"Why does he get the chance to come out and make another life, man? I mean my daughter doesn't get to come back, it just doesn't seem fair. He gets out in 25 years, you know?" said Joe Barbosa, Rosaura Hernandez's father.

Hilaire's official sentence will be decided on March 23.

Hernandez's parents have created an organization called "Justice for Rosaura," which helps those who are affected by domestic violence.

On Saturday, the family is having a domestic violence memorial walk. Saturday would have been Rosaura's 20th birthday.
