The father of a missing Hawaiian woman has died by suicide, Los Angeles police said.

At 4 a.m. Sunday, officers responded to the 6100 block of West Century Boulevard near Los Angeles International Airport to investigate the death, a police spokesman said.

The investigation revealed that 58-year-old Ryan Kobayashi, Hannah Kobayashi’s father, died by suicide, police said.

Ryan Kobayashi, who lived in Honolulu, and other members of his family were in Los Angeles looking for Hannah Kobayashi, who had taken a flight from Hawaii, where she lived, to Los Angeles on November 8. She was headed to New York City but had less than an hour to get to her departure terminal and missed a connecting flight, her aunt Larie Pidgeon said. Her family said Hannah Kobayashi decided to explore the area while waiting for a new flight.

On November 10, Hannah Kobayashi was recorded at a Nike event at The Grove mall, about 12 miles (20 kilometers) north of Los Angeles International Airport, but her family said they received text messages from her phone over the next few days.

In the last message, on Nov. 11, Hannah Kobayashi said she felt scared and worried someone would try to steal her money and identity, Pidgeon said.

Family members quoted one of the texts, according to a video report from Honolulu NBC affiliate KHNL: “I was pretty much tricked into giving away all my money to someone I thought I loved.”

A Nov. 15 Facebook post from the RAD Movement — a San Diego County nonprofit missing persons organization — states that surveillance video in the area of ​​Pico Boulevard and Hill Street in downtown Los Angeles showed Kobayashi with someone can be seen, which causes concern.

“From the images it appears that Hannah does not appear to be in good condition and that she is not alone,” the post said. “Due to the ongoing and active nature of this investigation, we cannot share any further details at this time.”

It is not clear when the video was recorded.

“There is reason to believe from video surveillance that Hannah is not doing well,” Pidgeon said a week ago, adding that the family did not want to discuss details because they did not want to hinder the investigation.

A Los Angeles police spokesman said Monday that no further information was available and that the investigation was ongoing.
