The search for a missing Auburn University student in Japan remains underway as investigators continue looking for answers following his May 29 disappearance in Kyoto.

Japanese authorities searching for James “Weston” Higginbotham, a 20-year-old Auburn junior from Hoover, told ABC News they believe it is “highly probable” that he left his family intentionally, though police said they remain concerned for his safety.

Higginbotham was reported missing after disappearing May 29 while traveling in Kyoto with family members. According to police, his parents contacted authorities after he stopped responding to messages and his phone location was turned off.

Investigators have interviewed family members, reviewed surveillance footage, examined belongings Higginbotham left behind and tracked his movements after leaving the family’s hotel, according to the report.

Despite the assessment that he may have left voluntarily, authorities continue to actively search for him.

Police said helicopters and K-9 teams are deployed in mountainous areas and hiking trails around Kyoto.

Authorities also noted concern for Higginbotham’s well-being because he does not speak Japanese.

The case has attracted significant attention from family, friends and supporters who have continued sharing information online in hopes of locating Higginbotham.

Higginbotham is a native of Hoover and is majoring in biosystems engineering at Auburn University.

In a statement, Auburn University said, “Our thoughts are with Weston, his family, friends and loved ones during this difficult time.”

Hoover Mayor Nick Derzis also offered support to the family, saying he is praying for Higginbotham’s safe return and for the family as search efforts continue.

Police said that if Higginbotham is located, authorities will respect his wishes and privacy.
