In the quiet city of Yuma, Arizona, Adrienne Heredia, a 29-year-old mother of four, was building a life with her partner, Luis Rios. That life was brutally extinguished on Friday, June 24, 2005, in a crime that would leave the community shaken and a family destroyed. The tragedy that unfolded inside their home on La Mesa Street was not a random act of violence, but a calculated and cruel betrayal by someone they knew and trusted.
On that summer evening, police responded to reports of
gunshots and screams at the residence. In the backyard, they found 35-year-old Luis Rios, who had been shot multiple times. He was rushed to a nearby hospital but died from his injuries. Fearing a hostage situation, officers cautiously entered the home. Inside, they made a devastating discovery: the bodies of Adrienne and four children. Adrienne had been asphyxiated.
The scene was one of unimaginable horror. Two of Adrienne’s children had also been killed: her 9-year-old daughter, Inez Newman, was asphyxiated, and her youngest child, 6-year-old Danny Heredia III, had been bound with electrical cords and shot to death. Two other boys who were staying at the home, 13-year-old Andreas Crawford and 12-year-old Enrique Bedoya, were also found dead from asphyxiation. The investigation revealed that the killer had spent hours inside the house, carrying out the murders.
The case remained unsolved for years, despite over 1,300 interviews and thousands of tips from the public. Investigators, however, had a suspect in mind: Preston Alton Strong, a man who was considered Luis Rios's best friend. The motive, prosecutors would later argue, was money. Rios had frequently loaned money to Strong, who had a history of financial trouble, but had recently decided to cut him off. This refusal apparently led to a deadly confrontation.
Evidence linking Strong to the crime scene included his fingerprints on plastic bags found near the victims and his DNA on the steering wheel of Rios's abandoned vehicle. In November 2007, while already in custody on unrelated fraud charges, Strong was publicly identified as a suspect in the murders. The legal process was slow, and he was not formally indicted for the six killings until 2014. During this time, Strong was tried and convicted for another murder—the 2007 strangulation and bludgeoning of a Yuma physician, Dr. Satinder Gill, for which he received a life sentence.
In April 2017, after a trial that lasted months, a jury found Preston Alton Strong guilty of six counts of first-degree murder for the 2005 massacre. The prosecution detailed how Strong, a man the family had trusted, methodically killed Adrienne, Luis, and the four innocent children. For his crimes, which included the seven murders as well as numerous other felonies like kidnapping and armed robbery over his criminal career, Strong was sentenced to death.
The conviction and death sentence brought a measure of legal closure, but could never erase the profound loss. The case went through a lengthy appeals process, with Strong maintaining his innocence and alleging misconduct by law enforcement and the jury. However, in September 2024, the Arizona Supreme Court upheld his death sentence, affirming the jury's decision. Preston Strong remains on death row, a final consequence for a day of unimaginable violence that took the lives of Adrienne Heredia and five children, leaving a permanent scar on their families and the Yuma community.
