Girly Chew Hossencofft’s disappearance has often been surrounded by stories more extravagant than the evidence needed to explain the prosecution. The court record offers a different starting point: a woman who failed to arrive at work, blood in her apartment and an estranged husband who later admitted arranging her kidnapping and murder.

The central twist at Linda Henning’s trial was not a supernatural claim or a lurid rumor. It was a conflict over the meaning of physical evidence. Blood attributed to Henning was found in Girly’s apartment, a place Henning said she had never visited. The defense argued that someone else had put it there.
The person supporting that defense was Diazien Hossencofft, Girly’s estranged husband and an admitted participant in the crime. The jury had to decide whether his account of planting evidence could be believed. [1]
The missed day at the bank
Girly was a Malaysian citizen and permanent U.S. resident who had lived in Albuquerque since 1992. She began working as a bank teller in 1997. The federal court’s later review describes a reliable employee whose unexplained absence quickly concerned people around her.
She was last seen leaving work on September 9, 1999. When she did not appear the following day and could not be reached, friends and coworkers sought help.
The reviewed court record describes a prosecution that proceeded without recovery of her body and without a definitive account of the precise method of killing. Those gaps did not prevent charges, but they limited what anyone could responsibly say about her last moments. [1]
An apartment and a disputed presence
Investigators found blood evidence in Girly’s apartment. Testing attributed some of it to Henning, who was closely involved with Diazien.
For the state, this was a direct challenge to Henning’s denial that she knew Girly’s home. If she had never been there, prosecutors asked, why was biological evidence associated with her at the scene?
The defense did not simply concede that the blood established participation. It offered a different explanation: Diazien had planted it. That theory would allow the test result and Henning’s claimed absence to coexist. The question therefore was not only whose blood had been found, but how it had arrived.
The later federal review records defense efforts to challenge collection, handling and interpretation of evidence. It also distinguishes claims actually supported by testimony from allegations asserted after conviction. The magistrate concluded that the record did not establish the contamination or misconduct Henning claimed.
Two discoveries on the same day
The missed shift was not the only event on September 10, 1999. A highway worker found a tarp and clothing near Magdalena, away from the Albuquerque apartment. Testing linked blood on the recovered material to Girly. The discovery supplied a second place to investigate even though her body was never recovered. The map marks Magdalena as the nearby community, not a precisely established recovery point. [1]
The federal record also describes evidence that Henning bought a tarp at Home Depot on September 8. Its size and style corresponded to the recovered tarp. That was a comparison between commercially available objects, not a unique serial-number match. Its force depended on the timing and its relationship to the other evidence. The gallery preserves that limit rather than presenting a generic tarp as the actual exhibit. [1]
The bank left a quieter trail
Bank records were important because Henning denied having met Girly. The court's account describes an August 20 transaction in which Girly served Henning. Records also placed Henning at the bank on August 26 and September 3, although those visits do not establish that Girly personally handled each transaction. A routine business record therefore tested a specific denial without supplying an eyewitness account of the murder. [1]
Another witness described Henning pointing out Girly's apartment on September 17. That testimony and the bank record concerned familiarity: what Henning knew about Girly and her surroundings. Blood attributed to Henning at the apartment presented a different question—how it got there. Her defense maintained that Diazien had planted it. The prosecution asked jurors to evaluate these connections together. Keeping the claims separate makes the case stronger to understand, without making any disputed point sound more certain than the record permits. [1]
The husband’s admission
On January 14, 2002, Diazien pleaded guilty to Girly’s murder, kidnapping and other offenses. He admitted masterminding the kidnapping and killing while withholding a clear explanation of exactly how she died or where her body was.
His plea established his own criminal responsibility. It did not automatically establish Henning’s. The state still had to prove its charges against her in a separate trial.
Diazien then became an unusual defense witness. According to the federal review, he testified that he had planted Henning’s blood in the apartment and that she had not participated in the kidnapping and murder.
The defense thus asked jurors to accept a specific part of the account of a man who had admitted arranging the crime. The prosecution relied on the physical evidence and other circumstances to argue that Henning was involved. Credibility could not be decided by treating every statement Diazien made as equally reliable merely because he had pleaded guilty.
The resulting trial was a contest between explanations of the same evidence. That is more revealing than treating the case as a series of unbelievable anecdotes. [1]
What other evidence could establish
The record describes additional testimony concerning Henning’s statements, her contacts with Diazien and items recovered during the investigation. Some evidence was inconclusive. For example, the existence of human blood on an object did not necessarily identify whose blood it was or establish the object’s role in a killing.
The difference between a connection and a conclusion is especially important in a case without a recovered body. Investigators may establish that people communicated, possessed certain items or handled property, while remaining unable to reconstruct the precise fatal act.
The prosecution combined those circumstances with the apartment evidence. Henning disputed their significance and later challenged numerous aspects of her representation and the state’s conduct.
Verdicts—and a partial reversal
Henning’s jury convicted her of felony murder, kidnapping, conspiracy and other offenses in 2002. Her original aggregate sentence was life plus additional consecutive years.
That original sentence should not be quoted as though every component remained untouched. On direct appeal, the perjury convictions were reversed because she had not received adequate notice. The other convictions were affirmed.
This was a meaningful legal correction, but it was not an acquittal of murder or a reversal of the entire case. Both parts of the appellate result belong in any accurate account: the perjury counts fell, and the remaining convictions survived.
The long challenge after trial
Henning later pursued state and federal post-conviction relief. Her federal petition raised a large number of complaints about the trial, her lawyers, evidence and prosecutorial conduct.
A magistrate judge examined the exhausted claims in a lengthy 2009 recommendation. A recommendation is not, on its own, the final judgment of the district court. The Tenth Circuit’s later order confirms that the district court reviewed the record, considered Henning’s objections and adopted the recommended findings and disposition.
In June 2010, the appellate court denied a certificate of appealability and dismissed her appeal. The court concluded that reasonable jurists would not debate the district court’s resolution of the claims under the governing standard.
These proceedings did not recover Girly’s body or settle every unanswered factual question. They determined whether the legal challenges presented justified relief from the surviving convictions. [1] [2]
The person behind the headlines
The record begins with a woman building a life in Albuquerque and people noticing when she did not arrive at work. Her disappearance became a criminal case because they sought answers and investigators followed evidence that contradicted innocent explanations.
Two different routes established criminal responsibility: Diazien’s guilty plea and Henning’s jury convictions, later modified by the reversal of the perjury counts. The uncertainty about Girly’s final moments remained a separate and painful part of the history.
Keeping those distinctions intact restores something the more sensational versions often lose. Girly was not a supporting character in other people’s bizarre claims. She was the person taken from her daily life, and the evidence and court proceedings were attempts to account for that loss.
