Suspect details and evidence that linked him to the crime
Suspect identification, charges, and legal outcomes
Cristhian Bahena Rivera, then 24, was an undocumented Mexican national working near the area through a labor contractor.

Investigators located bloodied jeans and boots matching his description during a warrant-supported search; DNA linked him to the remains. He was arrested on August 22, 2018, and charged with first-degree murder, kidnapping, and evidence tampering. On March 19, 2021, he entered a no contest plea to first-degree murder and was sentenced to life imprisonment without the possibility of parole.

Reliable information comes from court filings, verified law‑enforcement briefings, and major news outlets citing official records. When evaluating updates, check whether sources cite court documents, direct quotes from investigators, or named agencies; avoid posts that rely on anonymous claims, altered screenshots, or emotionally loaded language lacking corroboration.
