“Her skin was getting a little blue, starting to get some goosebumps,” described Martin. The deputy said there was a 15-foot retention wall next to the creek that made it difficult for bystanders to help.

Firefighters from Foothills Fire Rescue and West Metro Fire created a rope system to get a stokes basket across the creek to the Weimar. Rescue crews were able to pull her across the creek and back up to the highway, where an ambulance was waiting.

“We sign up to help people whether they’re in the river or on the side of the road,” said Martin. He and his colleagues credit the bystander who remained with Weimar while authorities were on their way.
