Sederbaum told KOMO News that at one point his entire head was inside the cougar's mouth, but when his friend began to run away, the cougar dropped him and chased Brooks.

He then rode his bike to try and find reception so he could call 911.

The injured man called 911 just after 11am, and shouted: 'Can you hear me? Help!' The call then cut out. 

Sederbaum survived the attack but was rushed to Harborview Medical Center with serious injuries.

'The cougar had actually dragged the victim back to the wood line and he was found dead there,' Sargent Ryan Abbott from the King County Sheriff's office said.
