Avondale, AZ – In a chilling case that has gripped the community, Emilio Rivera, an 18-year-old from Avondale, Arizona, has been charged with the murder of his 17-year-old ex-girlfriend, Rhiana Kemplin. Authorities say Rivera used his mother’s Glock handgun to fatally shoot Kemplin while she was asleep in her home, before threatening her mother in a terrifying confrontation.
The incident unfolded on November 8, marking a tragic and violent end to a tumultuous relationship between the two teens. This case highlights ongoing concerns around domestic violence and gun safety in domestic settings.
The Fatal Night: A Violent Encounter in the Home
According to court documents and eyewitness accounts, Kemplin’s mother encountered a masked man inside their apartment early in the morning. The suspect—believed to be Rivera—aimed a gun at her and attempted to fire, but the weapon did not discharge, producing a “clicking” sound. The man then fled, and the mother immediately found her daughter with a gunshot wound to the head.
“The bullet entered the right side of her head, exited through the left side, and also hit her left hand,” court reports detailed. Kemplin was rushed to the hospital but was later declared brain dead and passed away the same afternoon.
Disturbing Details: Tire Slashing and Charges
After the shooting, Rivera was brought in for questioning. Despite denying possession of a weapon and involvement in the shooting, Rivera confessed to visiting Kemplin’s apartment late at night, where a physical altercation occurred.
He admitted to slashing the tires on multiple cars in the apartment complex parking lot to limit Kemplin’s mobility, totaling damage to 14 vehicles. This act of vandalism led to multiple criminal damage charges against him.
- Rivera lived just a few minutes away from Kemplin’s residence.
- He claimed the fight broke out after accusing Kemplin of cheating.
- His mother’s 9mm Glock 43 handgun was found during a police search.
- Ballistics confirmed the same gun was used in Kemplin’s shooting.
Legal Proceedings and Community Impact
Following the arrest, Rivera was charged with first-degree murder and attempted second-degree murder. The judge set a $1 million bond, with his next court appearance scheduled soon. Authorities continue to investigate this heartbreaking case, which is being closely followed by local media and residents.
Police reports emphasize the serious risks posed by domestic conflicts escalating into violence, especially where firearms are readily accessible.
