The 25-year-old victim is a Chinese national, who teaches Chinese language at Maryknoll School.

Maryknoll School officials declined to be interviewed citing the police investigation, but shared the following statement: “We were devastated to learn that one of our visiting Chinese language teachers was the victim of this senseless off-campus attack. A valued member of our Maryknoll School community, she is in her second year as part of an international exchange program.

“We have notified our partner school and the Chinese Embassy and have offered our support. Our thoughts and prayers are with her and her family and friends during this most difficult time.”

The Honolulu Star-Advertiser also contacted Planet Fitness this morning.

Manager Adan Mendoza said he worked the night of the attack, but the fitness center’s personnel have been instructed by their supervisor not to say anything about the events of the night at this time.

“Nobody so far has recognized the person in the video,” he said, including himself.

“It’s tragic,” Mendoza said. “It’s crazy that something like this would happen. I just don’t understand it — the type of person it takes to do something like that and just walk away nonchanlantly. It’s got to be a broken person to pull something like that.”
