Joseph Blea: Crimes, DNA Evidence, and West Mesa Connection

Joseph Blea is an Albuquerque landscaper and convicted serial rapist who was sentenced in 2015 to 36 years in prison for the 1988 kidnapping and sexual assault of a 13-year-old girl, with DNA later tying him to assaults on three more victims and making him a suspect in the West Mesa murders. He was identified more than two decades after his first known attack through a DNA match generated under New Mexico’s Katie’s Law, which requires DNA collection from people arrested for felonies.1

The Attacks and the Victims

Investigators have described Blea as a serial rapist who targeted dozens of teenage girls in the late 1980s and early 1990s in a neighborhood near McKinley Middle School in Albuquerque. He wore a ski mask, carried a knife, and took his victims’ underwear. He worked as a landscaper, and for years his identity was unknown to police despite a clear pattern of assaults in the area.

The crimes behind his convictions span 1988 to 1993 and involve four identified victims. The first, identified in court records as A.W., was 13 years old when she was sexually assaulted at knifepoint in her home after school on November 2, 1988. A rape kit was collected at the time, but DNA technology could not identify the attacker, and the case went cold. Three more victims were assaulted in 1990 and 1993, including a 29-year-old student stalked and raped at knifepoint after Blea broke into her apartment on October 7, 1990.

How DNA Identified Him

Blea was arrested in 2008 on a domestic violence charge that was later dismissed. Under New Mexico’s DNA Identification Act, known as Katie’s Law, a cheek swab was collected at booking and entered into the Combined DNA Index System. On January 13, 2009, his profile matched DNA from the 1988 rape kit.

Katie’s Law took effect in 2006, making New Mexico the sixth state to require DNA collection from felony arrestees. It is named for Katie Sepich, a graduate student raped and murdered in Las Cruces in 2003, whose killer was arrested repeatedly before a later booking finally produced the DNA sample that matched him to her murder.

In 2010, Albuquerque police obtained a search warrant for a fresh DNA sample from Blea. Forensic scientist Donna Manogue determined that he could not be excluded as the source of the foreign DNA in the 1988 rape kit, and further testing linked him to evidence from three other victims. He was indicted in two separate cases.

Conviction and Sentence

Blea’s first case, covering the 1988 assault, went to trial in June 2015. He waived his right to appear, and a jury convicted him on stipulated facts read in open court. On June 8, 2015, District Court Judge Judith Nakamura sentenced the then-58-year-old Blea to 36 years in prison: 18 years for kidnapping and 18 years for first-degree criminal sexual penetration. Two additional victims submitted letters describing their assaults for the sentencing hearing. Nakamura told Blea, “In all honesty Mr. Blea, you took her life away.” Blea declined to make a statement beyond saying, “At this time I think it would be best if I refrained from saying anything.”

Soon after, Blea entered a conditional no-contest plea in a second case covering three more victims. He pleaded to five counts of first-degree criminal sexual penetration and one count of kidnapping, with the state agreeing to a sentencing cap of 54 years and sentencing set for July 30, 2015. The conditional plea preserved his right to appeal on three issues: the constitutionality of Katie’s Law, the statute of limitations, and the validity of the 2010 search warrant.

Appeals

Every court that heard Blea’s challenges rejected them.

The New Mexico Court of Appeals consolidated his two cases and affirmed his convictions on June 21, 2018. Judge Vigil, writing for the panel, upheld Katie’s Law on its face under the reasoning of the U.S. Supreme Court’s 2013 decision in Maryland v. King, which treated DNA collection from arrestees as a reasonable booking procedure comparable to fingerprinting. The court found the cheek swab a minimal intrusion against the state’s interest in identifying suspects and solving crimes. New Mexico Attorney General Hector Balderas called Blea a “serial child rapist” and said the ruling demonstrated the law’s value in cold cases where victims cannot identify their attacker.

In 2020, Blea filed a federal habeas corpus petition under 28 U.S.C. ยง 2254, arguing that his prosecution violated the Ex Post Facto Clause because the original 15-year statute of limitations would have barred the case before he was identified. New Mexico eliminated the time bar for first-degree felonies in 1997, and Blea contended that change could not apply to him. He also claimed ineffective assistance of counsel for not raising the limitations issue. A magistrate judge recommended denial, reasoning that the 1997 amendment was enacted before the original limitations period had expired and was therefore permissible under Stogner v. California. The federal district court dismissed the petition with prejudice. On August 1, 2024, the Tenth Circuit denied a certificate of appealability, writing that “reasonable jurists could not debate the district court’s dismissal” and that “counsel cannot be ineffective for failing to raise a claim that lacks merit.”

Blea petitioned the U.S. Supreme Court for certiorari on December 27, 2024, after Justice Gorsuch granted an extension. The Court denied the petition on April 28, 2025, and denied rehearing on August 18, 2025, ending his federal appeals.

The West Mesa Murders Connection

Blea is a suspect, but has not been charged, in the West Mesa murders. On February 2, 2009, a woman walking her dog on Albuquerque’s west side found a human bone protruding from the ground. Investigators later unearthed the skeletal remains of eleven women and one unborn child from makeshift graves near 118th Street and Amole Mesa Road. The victims ranged in age from 15 to 32. Ten had known ties to drugs and prostitution; the youngest, 15-year-old Jamie Barela, did not.

Two pieces of evidence connect Blea to the case. His DNA was found on the jeans of a woman murdered and dumped in the late 1980s. A tag from an Albuquerque nursery where he frequently shopped for his landscaping work was recovered from the burial-site debris. Police have said they do not have enough evidence to arrest him. Another person of interest, Lorenzo Montoya, has been described by Albuquerque police as the “prime suspect”; he died in 2006, and the disappearances in the area stopped around that time. The investigation remains active, and a $100,000 reward is available for information leading to a conviction.

Where He Is Now

Blea is incarcerated at the Otero County Prison Facility in Chaparral, New Mexico. With the Supreme Court’s denial of rehearing in August 2025, he has no known remaining avenues of appeal.
