Former Hawaii lawmaker Suzanne Chun Oakland remembers arriving at school one morning in 1977 to an eerie buzz.
The 15-year-old had met up with girlfriends as usual before class at Honolulu’s McKinley High School when she learned a student named Dawn Momohara had been found dead on the second floor of a school building.
“I don’t know how we got word of it, but everything spread really quickly,” Chun Oakland said.
Chun Oakland didn’t know Momohara, who was 16, but the unsolved death has haunted her and other McKinley students and staff for nearly half a century. That was until last week, when police used advances in DNA technology to arrest a 66-year-old resident of a Utah nursing home.
The suspect, former McKinley student Gideon Castro, was scheduled to make an initial court appearance Friday before a judge in Salt Lake County District Court. He remained in custody Thursday with the bond for his release set at $250,000, according to Salt Lake County Sheriff’s Office records.

Castro’s attorney, Marlene Mohn, did not respond to email and phone messages seeking comment.
Momohara had been sexually assaulted and strangled, police said.

“I was just really sad,” Chun Oakland recalled earlier this week. “I think for our student body, of course there’s that concern that what if he’s still out there and he does it to somebody else.”

On March 21, 1977, shortly after 7:30 a.m., Honolulu police found Momohara dead. She was partially clothed and lying on her back with an orange cloth tied around her neck, said Lt. Deena Thoemmes, of Honolulu Police. A subsequent autopsy ruled Momohara was strangled to death, and the medical examiner said there were signs of sexual assault.
Details from more than four decades ago are fuzzy for 1967 McKinley graduate Grant Okamura, who was the school’s 28-year-old band teacher in 1977, but the morning Momohara was found has remained a core memory.
Momohara’s sister — one of his flute players — arrived at school that day not knowing her sister had been found dead, he recalled. The sister was called to the office and later walked into the band room, devastated.
“The other students were trying to console her,” Okamura said. “At that point, I couldn’t have band. How do you have a class? She just sat there crying.”
She didn’t return to school for weeks afterward.

He doesn’t remember the sister’s name. The Associated Press was unable to make contact with any possible relatives. Okamura said he met Momohara a few times when he let her into the air-conditioned band room to wait for her sister.
The morning before Momohara was killed, she got a call from an unknown male and told her mother she was going to a nearby shopping center with friends. That was the last time her mother saw her, police said.
Police released sketches of a person of interest and a possible vehicle described by witnesses as a 1974 or 1975 Pontiac Lemans. A witness reported seeing the car when he and his girlfriend drove through campus the night before Momohara died. The witness saw a man and the car on the grass near the school’s English building, Thoemmes said.

The witness circled back around but the car and the man were gone.
Police were unable to identify a suspect and the case grew cold, though grief lingered over the campus.
Although police retrieved an unknown man’s DNA sample from the teenager’s clothing, they could not identify a suspect. Authorities would not develop meaningful leads in the homicide until decades later.
In 2019, cold case detectives asked a forensic biology unit to examine several items of evidence from the scene, including Momohara’s underwear. They were able to develop a DNA profile in 2020. Then, in 2023, police received information about potential suspects, two brothers who were interviewed in 1977.

Several days after Momohara was killed, detectives interviewed Castro, who graduated from McKinley High in 1976. He said he met Momohara at a school dance that year and last saw her at a carnival on campus in February 1977. Police interviewed his brother, who also met Momohara at the dance.
In November 2023, Honolulu police went to Chicago, where the brother was living. They “surreptitiously” obtained DNA from one of the brother’s adult children, Thoemmes said.
Lab findings excluded the brother as a suspect, but a DNA sample from Castro’s adult son, and later from Castro himself, proved he was responsible, Thoemmes said.
He was arrested last week at the nursing home where he lived in Millcreek, just south of Salt Lake City, on suspicion of second-degree murder.
Neither Okamura nor Chun Oakland remembered Castro.

Chun Oakland graduated in 1979 and grew up to become a Democratic member of the Hawaii Senate. She said Momohara’s killing bothered her over the years, especially when she would meet victims through her work as a lawmaker or as a board member of the nonprofit Sex Abuse Treatment Center, a statewide program provding services for sexual assault survivors.
Chun Oakland said she is grateful an arrest was possible even after all these years.
“I think the community in general, and our elected officials, they know the importance of trying to preserve the evidence that can someday be able to see justice for that individual or individuals,” she said.

A boy was killed after being struck by a vehicle today in Hawaii Kai, police said.
At about 11:02 a.m., a 37-year-old woman “was attempting to travel northbound” on Kukuau Place when the vehicle hit a boy who was in the road in front of the vehicle, according to a Honolulu Police Department’s Traffic Division news release. The child was taken to a hospital in critical conition where he was pronounced dead.
The driver remained at the scene and was uninjured, police said.
HPD did not release the boy’s age or say whether speed, drugs or alcohol were possible factors in the collision.

This was Oahu’s ninth fatality in 2026, compared with 15 at the same time last year.
Leaders from Pacific Island nations and territories gathered this week at the East-West Center in Manoa for an inaugural diplomatic and business summit aimed at promoting private sector investments and contracts across island communities in Oceania.
Through Monday and Tuesday the Pacific Agenda summit brought representatives from more than a dozen countries and more than 80 companies, as presidents and prime ministers from across the region rubbed shoulders and held meetings with American corporate executives, investors and experts to discuss everything from infrastructure, energy, tourism, telecommunications and satellite technology.
Among the companies participating were national giants like Salesforce, Boeing, Google, SpaceX and JP Morgan along with local companies like L&L Hawaiian Barbecue, Hawaiian Airlines and Hawaiian Electric.
“Over these past two days, we have listened and shared through the roundtables and dialogues,” said Solomon Islands Prime Minister and Pacific Islands Forum Chair Jeremiah Manele as the summit wrapped up Tuesday evening. “I have noted some candid and frank discussions centered on the topics of this summit. Whilst the past and present may have influenced our perspectives, what we take forward as partners in commercial diplomacy following this summit is critical. Indeed, investment and security are inseparable and critical for prosperity.”

The summit was hosted and co-organized by the East-West Center, U.S. State Department and Oahu-based U.S. Indo-Pacific Command. It’s part of a long effort that is in part aimed at countering China’s growing influence across the Pacific Islands as the U.S. and its allies work to maintain a footing in strategically important island chains.
Many Pacific Island countries have signed onto China’s Belt and Road Initiative, a series of Beijing-funded infrastructure projects aimed at promoting trade with China. Some analysts argue that many of the projects are “dual use” endeavors that also may be supporting Chinese intelligence and military operations in the region.
“We’ve seen other countries coming in the Pacific in quite an aggressive manner,” said U.S. Deputy Secretary of State Christopher Landau. “And in a sense, maybe that’s not a bad thing, and it’s given us a little bit of a kick in the butt to up our game in this region.”
Palauan President Surangel Whipps Jr. told the Honolulu Star-Advertiser that it’s been something he’s brought up frequently with American officials, saying that U.S. government agencies are “helping us build infrastructure, schools, health care facilities, roads. But when it comes to private sector, we don’t see you. You’re absent, but China’s there. So what we want to see is we want to see U.S. investment. We want to see Taiwanese investment. We want to see Japanese investment in our islands. We want to see Australian investment.”
The U.S. military has been investing heavily in Palau on infrastructure to support its operations as it pursues port renovations, building radars and stockpiling weapons and equipment for a potential Pacific conflict.

It also has begun building a new fuel depot in Papua New Guinea to offset effects of the ongoing shutdown of Red Hill and working on airstrips and other facilities across the region.
INDOPACOM Commander Adm. Samuel Paparo told attendees and the summit “we do need you in the private sector to move in and to help us build the vibrant commerce that brings this infrastructure to life. I ask you to work with our partners to develop and connect markets, to lower risk, to enhance transparency and to ensure a level playing field.”
As the summit concluded, the U.S. Trade and Development Agency announced it would fund a “hospital relocation project feasibility study” around Palau’s Belau National Hospital — the only hospital in the small island nation — in hopes of rebuilding and modernizing the aging facility, with local company Architects Hawaii Ltd. taking on the work.
Several other Pacific Island leaders told the Honolulu Star-Advertiser they had reached memorandums of understanding with companies to work on future projects across the region. Manele said top issues for island communities included “whether our child has electricity to study at night and whether farmers can reach markets, whether digital connections allow young people to participate in the global economy.”
Gov. Josh Green, who sits on the EWC’s board of governors, called the summit “an extraordinary success from the East-West Center perspective to gather all of these leaders … a lot of serious business partners that are interested in looking at Hawaii as a potential bridge deep into the Pacific.”

Landau said that he foresees looking to the EWC more to engage with Pacific Island nations, saying “the location here in Hawaii makes it a natural choice.” But he said that it would ultimately take years as deals discussed at the summit actually take shape before anyone can measure the impact of the summit.
“We welcome the realignment of foreign policy, and this is the first step in engaging us,” Tongan Prime Minister Fatafehi Fakafanua told the Star-Advertiser. “I think it’s a smart move to use the private sector to encourage investment into the Pacific. Evidently, there is not that much U.S. investment in the Pacific Islands, and we think this is a great catalyst for us to deepen our relationship.”
During closing remarks, Manele told Landau he would like him to “to help us with the establishment of a Pacific trade investment office in the U.S. similar to those that we have in New Zealand, Australia, China, Japan and in Geneva. It will greatly help our efforts in connecting trade and investment opportunities for us into the future.”
But while Pacific Island leaders welcomed the attention of American officials and companies, many still have deep disagreements with the United States. This month President Donald Trump’s administration rescinded the 2009 Endangerment Finding, which allowed the U.S. Environmental Protection Agency to regulate greenhouse gas emissions that contribute to climate change.
Trump and much of his Cabinet have insisted that climate change is a hoax. The White House has been rolling back environmental regulations while seeking to boost production of fossil fuels, encouraging other countries to import American oil and coal and deriding renewable energy sources.

In a keynote opening the summit, Manele said “climate change remains the greatest security threat impacting our livelihoods, communities and economic prosperity. Rising seas and intensifying disasters erode development gains and strain national budgets. A flooded school or damaged hospital is not only a humanitarian issue, that is strategic one.”
Fakafanua said that during the conference his delegation had conversations with an American company on the prospect of underwater geothermal energy, a renewable source that could help Tonga become less dependent on imported fossil fuels.
“United States administration has prioritized some key areas that they’re focusing on,” Fakafanua said. “But at the same time, it’s a free conversation, and we’re also putting on the table our own priorities.”
