Nearly a month after Hannah Kobayashi, a 30-year-old aspiring photographer from Hawaii, was reported missing after she was last seen at Los Angeles International Airport, investigators say she intentionally missed her flight to New York City and may have disappeared voluntarily .

According to various media interviews with her family, Hannah traveled from her home in Maui to New York to visit an aunt and have a photography opportunity. She reportedly missed two connecting flights from Los Angeles on November 8th and 11th.

At a news conference Monday, Los Angeles Police Chief Jim McDonnell said that the LAPD “has reviewed U.S. Customs and Border Protection video surveillance that clearly shows Kobayashi crossing the U.S. border on foot into Mexico.” She was alone with her luggage and appeared to be uninjured.”

The LAPD also said Hannah walked alone through the tunnel at the San Ysidro port of entry into Mexico, according to footage reviewed. McDonnell added that Hannah’s missing person case will remain active until her safety is confirmed, but that the LAPD will not begin an investigation in Mexico.

The Associated Press reported that a post on Monday from the Facebook group “Help Us Find Hannah” – which has over 25,000 members but is a private page – said the family would close the group and not respond to messages about the case. It is not clear when this post was shared in connection with the LAPD conference.

McDonnell said at a Nov. 26 Police Commission meeting that Hannah “missed her connecting flight from LAX to New York, which the investigation indicates was intentional.” The LAPD did not immediately respond to Yahoo News’ request for comment.

Hannah’s sister Sydni Kobayashi disputed the theory “that Hannah missed her flight on purpose.”

Hannah’s family has told multiple news outlets that Hannah has not communicated with them since November 11th.

What we know about the search for Hannah Kobayashi

It’s not clear why Hannah missed her connecting flight from Maui to New York City at LAX for the first time on November 8th.

The family said they saw security footage of Hannah leaving the airport on Nov. 8 and again at the Grove shopping center on Nov. 9 and 10, which is about 12 miles north of the airport. On November 11th, Hannah posted on her public Instagram account about attending a Nike event at the Grove and was even spotted in a stranger’s YouTube video about the event filmed on November 10th.

Hannah then returned to LAX on November 11 but did not board a flight. That was the last time anyone received messages from Hannah’s cell phone number.

On November 15th, the LAPD Missing Persons Unit made a poster describing Hannah and stating that she was last seen at LAX on November 11th. The family also filed a report with the FBI.

Why did Hannah take a trip to New York?

In an interview with NewsNation on November 23, Hannah’s aunt Larie Pidgeon said that Hannah sent her mother a detailed itinerary for her stay in New York, including places she wanted to eat, museums she wanted to visit, and of a photo assignment “that.” was always on her “wish list” as a career opportunity. Pidgeon added that Hannah also reportedly paid “a few thousand dollars” for a hotel reservation in New York.

Hannah’s sister Sydni told CNN that Hannah and her then-boyfriend booked the flights to New York together and also planned to visit an aunt in upstate New York. They separated after booking the flights and agreed to continue the trip separately.

The ex-boyfriend, whose name has not been publicly released, was able to successfully board a connecting flight to New York on November 8 and was “extremely responsive and cooperative with the investigation,” according to Hannah’s family.

Hannah’s family tries to figure out what happened in Los Angeles

Pidgeon told USA Today that on November 11, the family “started receiving text messages” from Hannah’s number saying she “didn’t feel safe, that someone was trying to steal her money, that someone was trying to steal her identity to steal.” Pidgeon added that the messages sent to family and friends included “weird things, like her calling us baby, things that weren’t quite the normal way she speaks.”

“She texted (a friend) saying she was scared and couldn’t come home or something like that,” Sydni told HawaiiNewsNow. “They were just really weird text messages. …It doesn’t sound like her – like there’s just something wrong. So I wasn’t entirely sure. I don’t know if it was her or if someone else wrote.”

One of her recent texts reportedly said: “I just had a very intense spiritual awakening. I’m heading back to the airport to get to NYC. I might need some help getting there.

In addition to the text messages, the family also did not know the names of two people Hannah sent money to via Venmo on Nov. 10 – transactions that Yahoo News was able to verify because Hannah’s Venmo account is public.

The family also says there is security camera footage that shows Hannah and an unknown stranger at the Crypto.com Arena in downtown Los Angeles, allegedly on November 11th.

“It was confirmed that she was on the evening of November 11th. left the airport and got on the subway,” Pidgeon told CBS News. “She wasn’t alone. She was with an unknown person. This causes us great concern as it relates to the timing of her disappearance. Therefore, our focus now is on the Pico metro station.”

Yahoo News has reached out to several family members.

“If you see Hannah, please call 911 immediately,” the family said in a statement shared on Facebook. “Please get a photo if possible. Your quick action is crucial. If you can safely keep an eye on her until the police arrive, please do so.”

What happened to her father Ryan?

According to the Los Angeles Police Department, Ryan helped search for his daughter for two weeks and was found dead on November 24th. The county medical examiner’s office confirmed Monday that he died by suicide.

The Kobayashi family said in a statement that Kobayashi “tragically took his own life” after “searching tirelessly throughout Los Angeles for 13 days.”

“The family of Hannah Kobayashi urges the public to remain focused on finding her,” the statement continued. “Hannah is still missing and is believed to be in imminent danger.”
