State Labor investigators are winding up a report into what may have caused last year's Big Island zip line accident.
36-year-old Ted Callaway fell 200 feet to his death, after a tower he was working on collapsed.
Now Callaway's mother Ilene, is on a misison.
She launched her own blog tracking zipline legislation, hoping to spare others the anguish of losing a loved one.
Callaway says she is troubled by the lack of regulations in the state.
"But what makes it even worse, is that it could have been prevented, that's our belief. I was appalled when I realized all you need is a business license to construct a zip line," Callaway said.
Hilo police department recently shared a 218-page report with Callaway, which she says indicated the anchor supports for the zip line tower failed.
She is anxiously waiting the report of state labor investigators hoping to find out more.
Next week Wednesday marks six months since the accident killed her son and injured a fellow co-worker.
"I am I feel like we have a right to know why this happened to Teddy. We have a right to know that and I have not gotten answers really why," said Callaway.
Big Island Mark Nakashima has been trying to regulate eco-adventure tours.
His and others want to prevent fly-by-night companies or wildcat operations from popping up with no oversight.
"What we are are doing is to ensure that zip lines operating in Hawaii are up to national standards and they are health and safety standareds. So no one is just stringing cable between trees and putting some type of pulley on it," Rep. Nakashima said.
He is proposing an insurance requirement for zipline companies as a way to bridge the gap until an industry study is completed as a prelude to more extensive regulations.
"The industry itself wants to move past the accident. We need to look at the health and safety issues as well as the enviromental iimpacts of these activities and strike a balance between the two," said Nakashima.
Nakashima and other lawmakers asked for waiver on a 48-hour hearing notice to keep the Senate bill allive, in order to meet an internal legislative deadline.
The Senate bill hearing is scheduled for 11 a.m. Thursday.
