A Washington State man has been arrested after he allegedly confessed to killing and dismembering two women. 

Mauricio Nava-Garibay, 28, was taken into custody Thursday after police found the remains of a 57-year-old woman and a 30-year-old woman in an abandoned 2014 gray Honda Accord in Othello. A passerby saw blood on the hood of the car and contacted police.

Police found one victim's head and other remains in the backseat of the vehicle and the dismembered remains of the other victim in the trunk. 

Police saw Nava-Garibay walking away from the crime scene and took him in for questioning.

Police believe he was in a relationship with the 57-year-old woman and allegedly said he'd gotten into a fight with her in her home the day before her remains were found.

Nava-Garibay allegedly told police he lured the woman into the garage and told her he had a gift for her.

"When getting in the garage, Mauricio told [victim] he had a gift for her and had her get inside the Honda," states a probable cause statement obtained by PEOPLE. "While inside the rear passenger seat, Mauricio stabbed [victim] in the neck with a green knife, punched her in the face, stabbed her multiple times in the torso, and strangled her with his belt and an extension cord."

Nava-Garibay allegedly killed the second victim, who had developmental disabilities, when she entered the garage.

"Mauricio pushed her from behind causing her to hit the side of the car, turn around, and fell on her back onto the concrete garage floor," the statement reads. "Mauricio turned her head and cut the back of her neck. Mauricio advised either the blow to the head from the fall or cutting her neck caused her to die."

According to the probable cause statement, Nava-Garibay allegedly dismembered the bodies because "they were too heavy to lift into the Honda." 

Nava-Garibay's blood-stained clothes were later found, police allege. 

He has been booked on charges of first-degree murder and removal or concealment of body. He is being held on $1 million bail. 

It is unclear if he has entered a plea or retained an attorney.
