A Hawaii man found dead in Los Angeles during a weekslong search for his missing daughter died by suicide, authorities confirmed Monday, prompting one family member to blame online conspiracy theories for his death.

It’s been two weeks since Hawaii woman Hannah Kobayashi went missing after she did not board a connecting flight to New York City during a layover at Los Angeles International Airport on 8.

The sister of Hannah Kobayashi, the Hawaii woman who vanished while heading to New York City, shared a moving tribute Tuesday to their father, who jumped to his death during the ongoing search for his still-missing daughter.
