HILO >> The mother of a man killed when a zip line tower collapsed on the Big Island wants Hawaii to regulate those attractions that allow riders strapped to a harness and a cable to glide above forest canopies. 

Thirty-six-year-old Ted Callaway died in September when he and a co-worker were in the process of testing a zip line north of Hilo. The tower collapsed and Callaway plunged 200 feet to his death.

His mother Ilene Callaway tells the Hawaii Tribune-Herald that she wants to ensure Hawaii’s growing zip line industry has stricter regulations.

But a bill earlier this month has been deferred that would have required the Department of Labor and Industrial Relations to conduct $100 inspections. 

Callaway’s family is looking into a lawsuit against those responsible for his death.
