Anatomy of a Murder Trial: Hernandez Melgar and the Evidence That Convicted Without DNA

On June 22, 2026, the Snohomish County Superior Court concluded one of the most instructive criminal trials in recent Washington state history. The case of State of Washington v. Nestor Hernandez Melgar sits at the intersection of forensic ambiguity and circumstantial sufficiency. No DNA linked the defendant to the victim’s body. The medical examiner refused to call the death a homicide. And yet — the jury returned guilty on all counts.

Here is how that happened.

1. The Charges

Nestor Hernandez Melgar, 29, faced four charges when the trial commenced:

• First-Degree Murder — the allegation of premeditated or intentional killing
• First-Degree Burglary — in this domestic context, the “unlawful entry” element was substantiated by Melgar’s presence in Geary’s residence while a no-contact order was active
• Violation of a Court Order — addressing the breach of a documented protection order issued two months prior to the death
• Domestic Violence Aggravator — a legal enhancement allowing the court to impose a sentence beyond the standard range, acknowledging the heightened nature of crimes committed within intimate relationships

The charges arose from a conflict between two stories: the defendant’s account of a suicide, and the state’s evidence of a documented history of domestic litigation — including multiple police contacts and a reported attempted break-in just eight days before Lindsay Geary’s death.

2. Two Narratives

Every criminal trial is a competition between divergent accounts of the same events. In Hernandez Melgar, those accounts were irreconcilable.

Prosecution’s narrative — “The Staged Suicide”: Melgar intentionally killed Geary using a rope and staged the bathroom scene to mimic a suicide. His actions afterward — calling family members before dialing 911, taking more than 90 seconds to open the door for arriving officers — were consistent with scene management, not grief.

Defense’s narrative — “The Tragic Suicide”: Geary, suffering from depression and a blood alcohol content of .228, took her own life. The defendant discovered his girlfriend dead and acted from shock. Her phone contained searches consistent with suicidal ideation and a draft message that resembled a suicide note, found by investigators in December 2025 — more than a year after her death.

Both narratives rested on different categories of evidence.

3. Circumstantial vs. Forensic Evidence

Circumstantial evidence requires the jury to make a logical inference from a fact to a conclusion. The prosecution’s circumstantial case included:

• The 911 delay: Melgar contacted family members before emergency services, suggesting scene presentation over life-saving
• The door delay: First responders waited approximately 90 seconds for Melgar to open the door — time the prosecution argued was used for final staging
• Rope length: The rope was 7.5 feet long; the prosecution argued this was physically incompatible with the logistics of self-hanging as the defense described it
• Litigation history: An active no-contact order and prior domestic disputes established the motive framework required for first-degree murder

Forensic evidence is objective scientific data from the body or scene. Here, the forensic record was ambiguous:

• Toxicology: Geary’s BAC was .228 — the defense argued this level of intoxication exacerbated existing mental health struggles
• DNA exclusion: Forensic testing excluded Melgar’s DNA from the victim’s neck and fingernails — a key point the defense used to argue the absence of physical struggle
• The year-gap discovery: A digital draft message resembling a suicide note was found on Geary’s phone on December 27, 2025 — more than a year after her death. Both sides argued its significance, and the delay itself became a point of dispute

4. The Medical Examiner’s “Undetermined” Ruling

The medical testimony created the trial’s central hurdle. In forensic pathology, “cause of death” and “manner of death” are distinct findings:

• Cause of death — the physical mechanism: asphyxia due to ligature compression
• Manner of death — the human agency: undetermined

An “undetermined” ruling means science confirmed the physical mechanism of death but could not distinguish whether that pressure was self-applied or applied by another. The medical examiner’s report took seven months to produce, reflecting the depth of that ambiguity.

When the medical record is inconclusive, the burden of interpretation shifts entirely to the legal proceedings. The jury, not the medical examiner, would have to resolve the question science could not.

5. The Verdict

On June 22, 2026, after four weeks of testimony, the jury returned Guilty on all charges, including first-degree murder with the domestic violence aggravator.

Three things that verdict teaches us:

1. Circumstantial evidence is legally sufficient. Washington state law holds that circumstantial evidence carries equal weight to direct evidence. A chain of behavioral facts — the call sequence, the door delay, the rope length — can support a murder conviction in the complete absence of forensic linkage.

2. Juries can resolve what science cannot. A medical examiner is bound by scientific certainty and must rule “undetermined” when data is balanced. A jury is tasked with the total picture. This jury concluded that the behavioral evidence answered what the autopsy could not.

3. The burglary charge was not incidental. By convicting on first-degree burglary, the jury found that Melgar’s presence in Geary’s apartment was itself a criminal act. The prosecution successfully argued that his entire time in that apartment was criminal — not just the moment of her death.

Nestor Hernandez Melgar is scheduled for sentencing on July 22, 2026.
