UPDATE 7:20 P.M. | The boy has been identified as Jackson Roos by his family, according to the King County Sheriff’s Office.
Detectives say the zipline seems to have been commercially made and installed. They are still unsure how Roos became entangled in the line.
A 12-year-old boy died after accidentally hanging himself on a zipline outside of Redmond this afternoon, according to the King County Sheriff’s Office.
Spokeswoman Sgt. Cindi West said it isn’t clear yet how the accident happened. She said it occurred in the 8800 block of 255 Avenue Southeast.
The 100-foot zipline is located on the large grounds of a home in unincorporated King County, according to the Associated Press. The boy’s mother thought he was out riding his bike when she went to look for him and found him hanging about 25-20 feet above ground, according to West.
