Photos from A Timeline of the Hannah Kobayashi Missing Person ...

Hannah Kobayashi Arrives in Los Angeles

On Nov. 8, Hannah Kobayashi flew from Maui to Los Angeles, where she was supposed to catch a connecting flight to New York's JFK International Airport, according to L.A. police.

Hannah was booked on the same flight as her ex-boyfriend. Her sister Sydni Kobayashi said, per the Los Angeles Times, that they couldn't get a refund on the seats but had agreed to go their separate ways upon arrival in New York, where Hannah was going for a concert and a photography job.

Hannah ended up not boarding her flight out of Los Angeles International Airport (LAX) for reasons unknown, per an LAPD news release. Her bag, meanwhile, was checked through to her final destination, and she requested it be sent back to LAX.

Surveillance video reviewed by police showed the 30-year-old picking up her bag at LAX on Nov. 11.

Hannah's Whereabouts in L.A.

Upon arrival in L.A., Hannah visited the Taschen bookstore at The Grove shopping center on Nov. 9 and texted a relative a photo of a book, her aunt Larie Pidgeon told the Los Angeles Times. Hannah also filled out a newsletter form, using her Maui address.

Family members used the photo data to track Hannah to Taschen, Larie explained, where they confirmed with employees that Hannah had been there. (Larie said she was one of the relatives who traveled from Maui to look for her niece.)

On Nov. 10, Hannah attended the LeBron XXII Trial Experience held at the Nike store at The Grove and posted a photo of Jordan-clad feet the same day, tagging the LA Times and putting her location as "City of Angels, Los Angeles CA." 

"We think she was staying around The Grove," Larie told the Times. "It's a pretty touristy area with a lot of shops, bookstores and museums, so we think she was just in that area sightseeing and felt safe."

Hannah's Texts Take a Concerning Turn, Family Reports Her Missing

Hannah's text messages to family members had sounded normal, including laments that she hadn't been able to get another flight yet, according to Larie.

But on Nov. 11, Larie continued, per the Times, Hannah texted another aunt that she was concerned her identity and all her money had been stolen, after which no one could get ahold of her.

"She was using words like 'hun' and 'babe' and saying 'someone's trying to steal my funds,'" Larie said. "She doesn’t talk like that. It was just out of character and the family sounded the alarm."

They were "strange, cryptic messages—things about the matrix, it was so unlike her," Larie told KTLA. "And then all of a sudden, no more communication."

The last time Hannah had her phone turned on was at 4 p.m. on Nov. 11 at LAX, where police said she picked up her bag.

Her family reported her missing the following day.

The Last Sighting of Hannah in L.A.

Hannah's family shared Nov. 18 that they had seen surveillance footage showing her getting off a train at the Pico Metro station near Crypto.com Arena in downtown L.A. at 10 p.m. on Nov. 11.

"It is evident that Hannah does not appear to be in good condition and she is not alone," her family wrote on Facebook.

According to police, Hannah made her way to Union Station, about three miles away from the arena, where she used her passport to purchase a bus ticket to a spot near the California-Mexico border.

On Nov. 12, police said, she boarded a bus to San Ysidro. The community has been dubbed the "Gateway to the Americas" as it's the most southern city in California and a popular border-crossing spot.

The Kobayashi Family Pleads for Help Finding Hannah

Family members staged a rally and passed out fliers on Nov. 21 near the downtown spot where Hannah was last seen

"Please, please do not stop saying her name, Hannah Kobayashi," her aunt Larie said at the event, per KTLA. "Your entire family is here. The entire world is looking for you. If you can and you have access, please reach out to us. We’re not mad." 

Added Hannah's father, Ryan Kobayashi, "She's a beautiful girl inside and outside. Just reach out, if you can at all."

He told NBC4 at the rally, "It’s every parents’ nightmare. We don’t know where to start, where to begin. It’s like a grain of sand in the ocean."

Hannah's Father Is Found Dead

Ryan Kobayashi, who was in town from Maui to look for Hannah, jumped to his death from a parking structure near LAX on the morning of Nov. 24, according to police, who responded to a report of a deceased male at the 6100 block of Century Boulevard at 4 a.m.

The L.A. County Medical Examiner's report stated that Ryan suffered multiple blunt force traumatic injuries and the manner of death was suicide.

"It's every parent's nightmare," Ryan told NBC4 at the Nov. 21 rally. "We don't know where to start, where to begin. It’s like a grain of sand in the ocean."

The RAD Movement, a nonprofit advocate for families of missing people, said in a statement Ryan had been in L.A. for 13 days searching for his daughter.

"This loss has compounded the family’s suffering immeasurably," the group stated, while also emphasizing that there was still a missing woman to look for and it was "crucial for everyone to remain vigilant in their efforts to locate Hannah."

Speculation that Ryan had something to do with Hannah's disappearance was cruel and needed to be shut down, Larie told the LA Times. "He died of a broken heart," she said.
