Adriana Herrera, a 40-year-old Hispanic woman, was fatally shot on January 3, 2025, in Las Vegas near east Tropicana Avenue and Nellis Boulevard. She was in a vehicle with her romantic partner, the ex-wife of the accused, when a man identified as 41-year-old Adrian Rodriguez-Guillen allegedly blocked their car, approached with a rifle, and opened fire. Herrera was killed at the scene from multiple gunshot wounds; the partner suffered a non-life-threatening hip wound.

Police say the shooting grew out of a troubled love triangle. Rodriguez-Guillen and his ex-wife had remained romantically involved after a 12-year marriage that produced seven children, but she began an on-and-off relationship about a year and a half earlier with Herrera, a coworker at Harry Reid International Airport. Two months before the shooting the ex-wife ended the relationship with Rodriguez-Guillen, and investigators say he had allegedly threatened to kill both women in the weeks that followed.

Rodriguez-Guillen reportedly stayed at the scene, apologized after his ex-wife was wounded, then called 911. He was arrested and charged with open murder with the use of a deadly weapon, attempted murder, kidnapping and other felonies, and is being held without bail. Does anyone who knew Adriana or was in that area that night have further information to share?
