Yolanda Valdez, a 35-year-old Hispanic mother of three, was tragically killed on November 7, 2013, in a shooting that erupted in a Sioux City, Iowa, home. Known for her bubbly and outgoing personality, Valdez had been making plans to move from Orange City, Iowa, back to her home state of California. Her life was cut short when she was caught in the crossfire of a violent altercation stemming from a drug-related dispute.

The incident unfolded in the attic of a house on the city's west side, where a group of people had gathered. An argument broke out between Juan Nino-Estrada and Luis Sanchez, a drug dealer who lived at the residence. The confrontation quickly escalated, with Nino-Estrada drawing a gun and pointing it at Sanchez. At that moment, Michael Delgado, 35, who was also in the house, entered the attic armed with a gun and confronted Nino-Estrada.

A scuffle ensued between Nino-Estrada and Delgado on the stairway landing, and multiple gunshots were fired. In the chaos, both Delgado and Valdez were fatally wounded. Sanchez was also shot and stabbed but ultimately survived his injuries. Tragically, it was determined that Valdez was an innocent bystander, struck by a stray bullet during the violent exchange.

Following the shooting, Juan Nino-Estrada, then 26 years old, was arrested and charged with two counts of first-degree murder for the deaths of Yolanda Valdez and Michael Delgado. He was also charged with the attempted murder of Luis Sanchez. During his trial, Nino-Estrada's defense claimed he acted in self-defense, arguing that he was in a "die or survive" situation. However, the jury rejected this claim and found him guilty on all counts.

In July 2015, Juan Nino-Estrada was sentenced to two consecutive life sentences in prison. His subsequent appeals, which argued ineffective legal counsel, were denied by the Iowa District Court of Appeals, upholding his conviction. The court affirmed that Nino-Estrada was responsible for the deaths that occurred during the drug-related shooting he initiated.
