On November 8, Hawaii woman Hannah Kobayashi boarded a flight from Maui to New York City, with a short layover in Los Angeles.
But after missing her connecting flight, Hannah vanished.
There were a few brief sightings of the 31-year-old in LA and family members have received concerning, out-of-character texts from her phone, but weeks later Hannah remains missing.

Now the body of her father, Ryan Kobayashi, has been found in LA after he spent almost two weeks desperately searching for his daughter.
Here's everything you need to know about Hannah's disappearance and the timeline of events since.
November 8
Hannah flew from Maui to Los Angeles, landing at Los Angeles International Airport (LAX) at 9.53pm local time.
She was seen on surveillance footage exiting the aircraft in a black hoodie and colourful leggings but never made it onto her connecting flight to New York City.
Her family said she missed it due to a tight 42-minute layover and was put on standby for a new flight.
Her sister Sydni Kobayashi told CNN that Hannah had the same itinerary as an ex-boyfriend but they intended to part ways in New York City.

November 9
The following day, Hannah was seen at The Grove, a popular shopping mall in downtown LA. Her family said she spent time at a bookstore there.
Hannah's aunt, Larie Pidgeon, told Fox News that her niece spent an hour and a half charging her phone at a Taschen bookstore and filled out a mailing list.
"It's in her handwriting," she told the outlet on November 21.
Sydni told CNN that Hannah also sent Venmo payments to two people that day.
Hannah's family did not recognise the individuals' names.
November 10
Hannah returned to the mall the following day and was visible in the background of footage from an event hosted at the Nike store there.
She also posted a photo from the event on Instagram with a single emoji of a speech bubble showing an eye inside as the caption.
November 11
Three days after Hannah landed in LA, her family and friends began receiving concerning texts from her phone.
In the messages, Hannah said she felt unsafe and claimed that someone was trying to steal her money and identity, according to her family.
"I got tricked pretty much into giving away all my funds," one text to a friend read, followed by a second saying, "For someone I thought I loved."
Another text sent to her aunt reportedly said: "I just finished a very intense spiritual awakening."

The texts used language that seemed out of character, according to Hannah's family, and were devoid of the emojis Hannah typically used.
"It's weird to me because it doesn't sound like her, like there's just something off about it ... I don't know if it's her or if someone else was texting."
Hannah was reportedly seen at LAX that same day, where Pidgeon said she spoke with an American Airlines ticketing agent in the hopes of getting a direct flight to New York City.
The family later shared that they also sighted surveillance footage that placed Hannah at the Pico Metro Station near the airport just after 10pm that night.
She reportedly left the station with an unidentified person and the family claim she did "not appear to be in good condition".
Hannah's phone last pinged at LAX on November 11 and has been turned off ever since.
November 12
Four days after Hannah touched down in LA, her family filed a missing person report with the Los Angeles Police Department.
A social media campaign was launched and police petitioned the public for any information about her whereabouts.
A post shared online described the 31-year-old as having brown hair and hazel eyes, freckles on her face and a tattoo of a knife on her arm.
She's 5'10" (177cm) and weighs 140lbs (63kg).
November 24
Hannah's father was found dead on Sunday, November 24, after almost two weeks spent searching the city for his missing daughter.
LAPD confirmed his body was discovered in a carpark at a business near LAX around 4am local time.
The suspected cause of death was not made public.
"I wasn't too close with her … growing up. We haven't had contact for a while," he had told CNN days before his death.
"I'm just trying to make up. I'm trying to get her back.
"That's my main focus."
Pidgeon told CNN the family was devastated by Ryan's death and said: "We also want to make it clear that Ryan died of a broken heart."
