Daylenn Moke Pua disappeared February 27, 2015, Haiku Stairs, Waianae, Hawaii. Remains never located.

Revised June 2024

Eighteen-year-old Daylenn "Moke" Pua vanished on February 27, 2015. He was last seen boarding a bus in Waianae, Oahu, Hawaii. Visiting Oahu from the Big Island, he had confided in his grandmother about his plan to hike the Haiku Stairs, also known as the "Stairway to Heaven," a perilous and off-limits trail. His grandmother had swiftly warned him against it, stressing the danger and illegality of the trek.

Despite her concerns, Moke set out on his hike and posted several photos on social media from his phone during the ascent. One particular image caught people’s attention, featuring a mysterious man in the background.

Moke never returned from the Stairs. Did the mystery man have something to do with his disappearance? Did Moke fall to his death on the treacherous steps, or did something more sinister occur that day?

Years have passed with no sign of Moke Pua—no remains, no clothing, no clues. The haunting mystery of what happened to him on that fateful hike endures, shrouded in silence and speculation.

Who was Daylenn Pua?

Moke lived in South Kona, a district on the Big Island of Hawaii, known for its Kona coffee and the Ironman World Championship Triathlon location. The term "Kona" sometimes refers to its largest town, Kailua-Kona.

He was an aspiring pastry chef and hoped to attend culinary school after graduating. His two other siblings attended the same high school, Ke Kula ‘O Ehunuikaimalino, a Hawaiian immersion school in Kealakekua, where he was a senior.

He had many friends and enjoyed spending time on the beach, photography, hiking and swimming.

What are the Haiku Stairs?

The Haʻikū Stairs, also known as the “Stairway to Heaven”, is a steep, 3,922-step steel structure providing foot access to former U.S. Navy communication facilities on the island of Oʻahu in Hawaii. The pathway spans the Oahu's Ko'olau mountain range, with views from the top to Kaneohe and Kaneohe Bay.

History and construction of the Haʻikū Stairs

Building the US Naval Radio Station in Haʻikū Valley was one of the most complex projects of World War 2 in the Pacific theater. The facility was classified as top secret, and there was no actual model to follow for engineering construction, as it had never been done before. It was also hazardous to construct as the terrain was extremely rugged. The groundbreaking design and construction of the Naval Radio Station is a testament to the courage and ingenuity of military and civilian personnel under the pressure of war. Once operational, the low-frequency radio system at Ha'ikū could send messages to submarines as far away as Tokyo Harbor.

Along with the shortage of workers and materials, there was also anxiety in Hawaii following the attack on Pearl Harbor on December 7, 1941.

Construction began in 1942 to create an antennae system that reached almost 3,000 feet across. However, the valley was covered with dense vegetation, large lava rocks, and huge intertwined hau trees.

Beyond clearing the valley, the most significant problem facing the construction of the radio station was finding a way to send men to the top of the cliffs. The cliffs that semi-encircle the valley range between 1,800 and 2,850 feet in many places, rising almost vertically. To add to the difficulties, the dirt was often either crumbly lava or muddy and unstable from the high rainfall and fog.

The contractors had considered sending back to the mainland for professional high-scalers when it was discovered that two such high-scalers were working on another challenging military project in nearby Red Hill. The two men, Bill Adams and Louis Otto, under the leadership of rigger Ray Cotherman, were known for their fierce determination and courage in conquering the heights. They began their climb up the steep slopes with one coil of rope, a rock pick sledgehammer, and some three-foot steel pins. It took Bill Adams and Louis Otto 21 days to scale 2,800 feet to the peak of Pu'u Keahiakahoe on Ha'ikū Valley's eastern wall.

Construction battalion forces later completed certain portions of the work, including “installation of the 600-KW diesel standby generator in the bombproof transmitter building, installation of several poles on the transmitter building on the Pali summit, and installation of a short length of underground cable.”

​The US Naval Radio station at Haʻikū Valley satisfied two requirements of the war. It allowed for long-range transmission and was built in a position that allowed excellent defence from enemy attack. The project was completed in December 1943, and over the 200 KW Alexanderson Alternator at Haiku messages to merchant ships, weather reports to naval vessels and despatches to submarines were broadcast.

Some remnant parts of the wooden ladder may still be seen beside the metal steps. The radio station was commissioned in 1943.

The Naval base was decommissioned in the 1950s, and the U.S. Coast Guard used the site for an Omega Navigation System station. In the mid-1950s, the wooden stairs were replaced by sections of metal steps and ramps, and the station and trail were officially closed to the public in 1987.

The disappearance of Daylenn Pua

Moke lived on the Big Island but was visiting his grandmother, Martha Bear, in Waianae.

He was interested in hiking up the Stairway to Heaven, but Martha told her grandson that it was closed and that authorities were not letting anybody climb the mountain due to safety concerns.

On Friday morning, February 27, 2015, Pua left his grandmother’s home and boarded a bus from Waianae, Oahu, never to return. He was wearing a white long-sleeved t-shirt, black surf shorts, and slippers and carrying a red backpack.

Pua posted a picture of the stairs on social media on February 25, 2015, with the caption: “Stairway to Heaven… hiking this insane hike tomorrow. Wish me luck.”

The final Facebook post on his account was on February 26, 2015, saying, “And the hike begins #haiku.”

There is a discrepancy in the reported dates surrounding Moke Pua's disappearance. Most sources claim he went missing on February 27, 2015, the day he was supposed to board a bus. However, his last Facebook post indicates he began hiking the Haiku Stairs on February 26. This raises questions: did he delay his hike by a day, or is the reported date of his disappearance inaccurate?

It's possible that Moke started his hike on the 26th and didn't return. After 24 hours, his grandmother reported him missing on February 27 when he failed to come home. This suggests he was officially reported missing the day after his hike.

The mystery man

Honolulu police reported that Pua texted pictures of himself on the Haiku Stairs trail around 11.00 am, despite having told his grandmother he wouldn't go. Since then, he has neither been seen nor heard from.

Moke's family scrutinized these pictures for clues and noticed a barely visible man lurking in the bushes in one of them. They suspected this mysterious figure might have been following Pua, though the authorities remained skeptical.

This raises several unsettling questions: Who was this man? Was he an innocent bystander or someone with sinister intentions? Could his presence in the photo be a mere coincidence, or was he stalking Moke? Did Moke realize he wasn't alone on the mountain? Why hasn't this man come forward—was it due to the illegal nature of the trail? Some accounts suggest he did, but this remains unconfirmed by the authorities.

While this mystery man might be a red herring, his appearance in Moke's photo adds a chilling layer to an already baffling case.

The search for Daylenn Pua

The search effort involved the Honolulu Fire Department (HFD), local volunteers, family, drone operators, and even the U.S. Navy. Helicopter pilots donated their time to fly around and search the Haʻikū Valley with Moke’s father on board, calling out his name over the sound of the rotor blades.

The poor weather, with lots of rain, made climbing the Haʻikū Stairs difficult and the surrounding steep areas almost impossible.

Some hikers reported hearing cries for help on the Monday following the disappearance, extending the fire department’s search to Tuesday, March 3, 2015, when the official investigation was suspended at 4.44 pm. Relatives and local volunteers continued to comb the area for any signs until March 5, with some even rappelling down the extremely steep and dangerous cliffs to check the end of the Kulana’ahane Trail, the location of Daylenn’s last picture.

In a Reddit post from 2015, someone called Dclandry, said:

“A lot of people have their information mixed up. I could never explain to you the feeling I felt when you hear a cry like that. The hiker did not trust pass and go up the stairs. By the looks of the photographs, he didn't even make it to the stairs. The hiker went up the Moanalua way. I'm not a local so I don't really know any of the name of the ridges, all I can do is try my best to explain to others where we went and where it was that we heard him. We started the hike on on a trail about 20 feet from the Kulana'ahane trail. We had hiked about three hours up. We were yelling to each other to make sure the others were okay because we were so far apart. The wind died down for just a half a second and we hear a scream "help me!" It shook my up so bad that I had to sit down to even call 911. My friends were about 50 yards in front of me and little did I know, they were also calling 911. All 5 of us heard it at the same time. If we were going straight at the trail, the voice was coming from the left. It was coming from down below. It did not seem as if it was echoing nor did it seem very far away. The scary thing is is that after about an hour,once the rescuers were there, my friend and I were bound and determined to get to the top of the stairs so we decided to continue one, and the other three stayed where they were. As we were continuing at the ridge we could hear the firemen/rescuers down below whistling and calling for him. Again, the wind died just a tad and we heard "I'm down here!" My friend and I both stopped in our tracks and started screaming for him. It was not the rescuers. The voice was different than The calls from the rescuers. I immediately called 911 again. We stayed up there for about another hour without moving to try and listen for him again. The wind was so bad and the clouds are starting to roll in so it was hard to hear anything.

My friend and I that heard the last cry, are heading up the ridge tomorrow the same way that we went Monday. It's hard to explain where the location was that we heard it, as well as where the voice was coming from. So in an effort to find him were going back tomorrow when I get off of work at 7.30am.”

But nothing was found. It was baffling for the authorities, friends and volunteer searchers.

The Authorities concluded that Daylenn had slipped and fallen to his death somewhere along the 'Stairway to Heaven' path. Daylenn Pua remains missing to this day, and no trace of him has ever been found.

What happened to Daylenn Pua?

No remains have ever been found, so people have theorized what might have happened. Heavy rains during the search hampered the use of tracker dogs or trackers who might’ve otherwise been able to follow his scent.

Accident

The Stairway to Heaven is dangerous, so it was closed to the public, a fact that Pua ignored. The stairs suffered considerable damage from a landslide in early February 2015. Some hikers were stranded after the landslide and had to be rescued on February 16, a week before Pua attempted the climb. After the landslide, the steps were even more dangerous and unstable, and with sheer drops on either side of the stairs, a slip could easily have been fatal. But, strangely, a body has never been found despite vast amounts of searching in the years since Daylenn vanished. Did a secondary landslide perhaps bury him?

Attacked

Did Daylenn Pua fall victim to foul play, as his family believe? The Honolulu Police Department examined the mystery man's photo and put out a CrimeStoppers alert asking for any information about him.

However, no one contacted the police and his identity and purpose remain a mystery. The authorities believe it is unlikely the man was involved.

Latest developments

The stairs are currently closed and illegal to access.

Friends of Haʻikū Stairs (FHS) is a group of volunteers whose mission is to protect the historic Haʻikū Stairs and the surrounding area for current and future generations. They filed a lawsuit on August 8, 2023, against the City & County of Honolulu, seeking a court order to halt the planned demolition of the Stairs on environmental grounds. The group said the city refused to negotiate in good faith to find an alternative solution, leaving them no choice but to take legal action.

The FHS say the cost of removal is $4.3 million with permitting, mitigation, and remediation​​ , which could also cause serious harm to endangered species living in critical habitats around the Stairs, causing soil runoff and harming the downstream watershed leading into Kāne‘ohe Bay. In addition, closing the Stairs diverts hikers to the Moanalua "back way," a far more dangerous route that has led to 7 HFD rescues in 2022m-2023. Therefore, FHS propose managed access, with costs associated with reopening the Haʻikū Stairs, including operational management and repair, which would be covered by non-government funds (e.g., private and non-profit). All liability would similarly be assumed by private entities, with 24/7 surveillance ending trespassing and unauthorized access once and for all.
