King County Sheriff’s Office Determined Helmet Strap Strangled Boy on Zip Line
SEATTLE (AP) — Investigators have determined that a bicycle helmet’s strap strangled a 12-year-old boy while he was riding a zip line installed at his home outside Redmond.
The King County Sheriff’s office says Friday that Jackson Roos died when a safety line caught the back of his helmet and pulled it up. It caused the helmet strap to tighten around his neck and cut off his air supply.
Detectives say the accident could not have been predicted.
Roos’ mother thought he was riding his bike around their home Wednesday when she went to look for him. She found him hanging from the zip line.
