HONOLULU — Nearly five decades after the brutal murder of 16-year-old Dawn Momohara at Honolulu’s McKinley High School, advances in DNA technology have led to the arrest of a suspect. Gideon Castro, a 66-year-old former student of the school, was apprehended in a Utah nursing home last week, bringing closure to a case that has haunted the community as 1977.
A Morning of Horror
On March 21, 1977, students and staff at McKinley High School were met with a chilling finding. Dawn Momohara was found dead on the second floor of a school building, partially clothed and strangled with an orange cloth. The crime scene suggested she had been sexually assaulted,according to Honolulu police.
“I don’t know how we got word of it, but everything spread realy quickly,” recalled Suzanne Chun Oakland, a former Hawaii lawmaker and McKinley high School alumna. “It was a day no one could forget.”
The Investigation That Went Cold
Despite releasing sketches of a person of interest and identifying a possible vehicle—a 1974 or 1975 Pontiac LeMans—police were unable to pinpoint a suspect. witnesses reported seeing a man and the car near the school’s English building the night before the murder, but by the time investigators arrived, both had vanished.
“The case grew cold, but the grief never left,” said homicide Lt. Deena Thoemmes, who has been involved in the investigation for years. “We never stopped looking for answers.”
DNA Breakthrough
In 2019, cold case detectives revisited the evidence, including Momohara’s underwear, and submitted it to a forensic biology unit. By 2020, a DNA profile was developed, and in 2023, investigators received a tip about two brothers who matched the profile.this led them to Castro, who was living in a Utah nursing home.
“Advances in DNA technology have revolutionized how we solve cold cases,” said Dr. Steven Armentrout, a computer science expert whose company, Parabon NanoLabs, specializes in forensic DNA analysis. “Even decades-old evidence can now yield actionable leads.”
The Arrest and Court proceedings
Castro appeared in court via video from a hospital bed in the medical wing of a Utah jail. He requested to hire his own attorney and was ordered to return virtually to Salt Lake County District Court for an initial appearance. His bond was set at $250,000, and he remains in custody pending extradition to Honolulu.
Marlene mohn,Castro’s court-appointed attorney,did not respond to requests for comment.
A Community’s Relief
For those who knew Momohara, the arrest brings a bittersweet sense of closure. “I was just really sad,” Chun Oakland said. “there was always that concern—what if he’s still out there and he dose it to somebody else?”
Grant Okamura, a former band teacher at McKinley High School, recalled the emotional toll the murder took on the school community. “Momohara’s sister was one of my flute players,” he said. “She walked into the band room devastated, and the students tried to console her. How do you have a class after that?”
The Future of Cold Case Investigations
This case highlights the growing role of DNA technology in solving cold cases. According to a recent study,advancements in forensic science have helped solve over 200 cold cases in the U.S. as 2018 [[1]]. Experts predict that as technology continues to evolve, even more long-unsolved cases will be cracked.
“We’re just scratching the surface of what’s possible,” said Dr. Armentrout. “The future of forensic science is incredibly promising.”

In a groundbreaking advancement, Honolulu police have successfully closed a decades-old cold case involving the 1977 murder of a young woman, thanks to advanced DNA technology and meticulous investigative work. The suspect, identified as 65-year-old John Castro, was arrested last week at a nursing home in Millcreek, Utah, on suspicion of second-degree murder. The case, which had remained unsolved for over four decades, highlights the enduring importance of preserving evidence and leveraging modern forensic science to achieve justice.
The Breakthrough: DNA Evidence Leads to Arrest
In November 2023, Honolulu detectives traveled to Chicago to investigate Castro’s brother, who had been interviewed in 1977. According to Detective Mark Thoemmes, the team “surreptitiously” obtained a DNA sample from one of the brother’s adult children. While lab results excluded the brother as a suspect, thay provided a crucial lead. Investigators then obtained a DNA sample from Castro’s adult son, which matched evidence from the crime scene. A subsequent sample taken directly from Castro confirmed his involvement in the murder.
“This case is a testament to the power of persistence and innovation in forensic science,” Thoemmes said in a press conference. “Even after 46 years,justice can still be served.”
The Victim: A Life Cut Short
The victim, 17-year-old Karen Momohara, was a student at McKinley High School in Honolulu. She was last seen alive at a school carnival in February 1977. Her body was discovered days later,and the case quickly went cold. Momohara’s death left a lasting impact on her community,particularly on her classmates,including former hawaii State Senator Suzanne Chun Oakland,who graduated in 1979.
“Karen’s murder has haunted me for years,” Chun Oakland said in an exclusive interview. “As a lawmaker and advocate for survivors of sexual violence, I’ve always felt a personal connection to her story. I’m grateful that her family can finally have some closure.”
The Suspect: A Quiet Life in Utah
Castro, who graduated from McKinley High in 1976, had lived a relatively quiet life in millcreek, Utah, before his arrest. According to police records, he had been interviewed in 1977 but was never formally charged. His brother, who also knew Momohara, was initially considered a suspect but was later cleared through DNA testing.
Neighbors described Castro as a reclusive figure who rarely interacted with others.“He kept to himself and didn’t seem like someone capable of such a crime,” said one neighbor,who asked to remain anonymous. “It’s shocking to think he could have been involved in something so horrific.”
Community Reaction: A Long-Awaited Resolution
the arrest has sparked a wave of relief and reflection in Honolulu. For many, the case serves as a reminder of the importance of preserving evidence and the potential for cold cases to be solved with advancements in technology.
“This arrest shows that justice doesn’t have an expiration date,” said Dr. Emily Carter, a forensic science expert at the University of Hawaii. “DNA technology has revolutionized criminal investigations, and cases like this demonstrate its incredible potential.”
Looking Ahead: The road to Justice
Castro is currently awaiting extradition to Hawaii,where he will face charges of second-degree murder. If convicted, he could face life in prison. The case has also reignited discussions about the need for increased funding and resources for cold case units across the contry.
“This is a victory for justice, but it’s also a call to action,” said Chun Oakland. “We must continue to support law enforcement and forensic science to ensure that no case is ever forgotten.”
