Hope Never Died: Sister of Murdered Teen Speaks After Cold Case Arrest

A Long-Awaited Justice for a 13-Year-Old Murder Victim

The emotional moment came as the younger sister of a 13-year-old girl stepped up to the podium during a news conference on Tuesday morning in Pasco. Nikki Cook, who was just 9 years old when her sister Anna Pelayo was murdered in 1997, expressed her feelings as the Franklin County sheriff announced the arrest of a suspect in the case.

Anna's murder occurred on December 28, 1997, when she was found shot in the head on the side of Taylor Flats Road north of Pasco. She was rushed to Kadlec Regional Medical Center in Richland, where she later died. For 27 years, the family held onto hope that justice would eventually be served.

On Monday, Jesse Lee Castillo, 51, was arrested in Union Gap on suspicion of second-degree murder. The arrest marked a significant breakthrough after years of investigation and advancements in DNA technology. While Castillo and Jose Luis Silva, 29, were considered persons of interest at the time of the crime, it wasn’t until recent developments in forensic science that investigators could directly link them to the murder.

Nikki Cook shared her gratitude with the Franklin County Sheriff’s Office and all those who worked tirelessly on the case over the years. She specifically thanked Detective Ramona Ramos, who was the same age as Anna would have been today. Ramos kept a picture of Pelayo at her desk while working on the case, showing her deep commitment to the investigation.

“I can see Anna in you,” Cook said. “I know you took her case to heart.”

Castillo appeared briefly in Franklin County Superior Court on Tuesday afternoon. His arrest followed a long period of investigation and persistence from law enforcement.

Impact on Law Enforcement and Community Protocols

Anna’s case had a lasting impact not only on her family but also on the broader community. Franklin County Sheriff Jim Raymond, who was a Pasco police sergeant on a narcotics task force at the time, recalled the emotional weight of the case. He struggled to hold back tears as he spoke about the tragedy.

Over the years, detectives returned to the case repeatedly, searching for evidence that could lead to an arrest. Commander Marcus Conner highlighted the importance of this case in shaping how local police handle reports of teens acting out.

In the days following the murder, Anna’s mother told the Tri-City Herald that her daughter had begun associating with gang members and running away from home after the family moved to Pasco from Richland. She had been a good student but felt the need for protection after being assaulted at Stevens Middle School. School officials confirmed the assault, and the sheriff’s office listed Anna as a runaway.

Conner noted that the case led to a shift in how law enforcement approached runaway situations. “We really don’t know how many lives Anna saved, because it shifted the mindset of law enforcement to take these cases seriously and look for causal factors behind changes in behavior,” he said.

A Relief After 27 Years

For Anna’s family, the arrest of Castillo brought a sense of relief after decades of waiting. Conner emphasized that both the family and law enforcement never stopped pushing for answers.

“We have not stopped investigating this, and we’re finally to that point thanks to the countless detectives that have worked on this over the years and the advancement of technology so we can put everything together and arrest Mr. Castillo for it,” Conner said.

The case serves as a reminder of the importance of perseverance, technological progress, and the impact one life can have on an entire community. As the search for justice continues, the legacy of Anna Pelayo remains a powerful symbol of resilience and change.
