AVONDALE, AZ (3TV/CBS 5) -- Police say a man was arrested on Interstate 10 in Tolleson after he shot and killed his girlfriend on Saturday night.
Court records say the incident happened about 10 p.m. alleging that 30-year-old Jesus Armando Leon-Serrano got into a fight with Marisol Serrano and shot her in the head while in their Ford Expedition parked outside their home near Buckeye Road and 107th Avenue in Avondale. Eventually, Leon left the scene in the Expedition.
Leon-Serrano apparently called his family after the shooting and his ex-wife contacted police thinking he was shot and provided police with information on his location on the eastbound I-10 onramp near 91st Avenue. When police made contact with Leon-Serrano, they found that he had blood on his shirt and arms. Police took him into custody.
Police searched the car and found Serrano in the front seat with a large amount of blood around her head and rest of her upper body. She was taken to Abrazo Hospital West Campus where she died from her injuries that ended up being a gun shot wound to the head.
Allegedly Leon-Serrano admitted to police that he shot Serrano in the head after days of arguing about their kids from past relationships. During an argument that evening, he said that he tried to get her to get out of the car but when she refused, he took out his handgun and pointed it at the back of her head. Leon-Serrano hoped that she would've been scared enough to get out of the car so he could leave. Instead, he says Serrano moved, hit his arm which caused him to fire the weapon that hit Serrano.
Court records also indicate that he left the scene with her in the SUV, called family, and threw the weapon out the window near the I-10 and 99th Avenue. Once he threw out the weapon, he told police that he got onto the I-10 and pulled to the side to wait for his family to arrive.
Leon-Serrano has been charged with second degree murder, disorderly conduct, and aggravated assault with a deadly weapon.
