Police in Eugene, Oregon, say a 39-year-old driver apparently set herself on fire, crashed her car on a bridge and jumped 40 feet to a park below.

The woman is being treated for critical injuries at a Portland-area hospital.

According to The Register-Guard newspaper (http://is.gd/ZBElBA ), someone called 911 Thursday afternoon and reported a car appeared to be on fire from the inside, with the woman at the wheel driving recklessly.

After the car crashed into a bridge guardrail, witnesses told police the woman jumped out — on fire — and began taking her clothes off as she ran to the edge of the span.

Police say truck drivers tried to put out the flames with fire extinguishers and another person tried to grab the woman, but she was still able to jump.

A police spokesman says the woman's family had recently reported her missing.
