The cyclists that were attacked by a cougar about 30 miles east of Seattle on Saturday, leaving one of them dead, have been publicly identified.

Thirty-one-year-old Isaac Sederbaum of Seattle remained in satisfactory condition at a hospital Sunday after being bitten on the head. Killed was 32-year-old S.J. Brooks, also of Seattle.

Authorities said they did everything right, getting off their bikes, making noise and trying to scare the animal off. One even smacked it with his bike after it charged.

The cougar ran off, but it returned and attacked when the men got back on their bikes. State wildlife agents used dogs to track the cougar and found it in a tree. They shot and killed it.

Authorities say the cougar that attacked the cyclists appears to have been emaciated.

Washington Department of Fish and Wildlife Police Capt. Alan Myers said Sunday that the cougar was about 100 pounds, when a typical 3-year-old male in the area would be 140 to 180 pounds. A necropsy will try to determine why the animal was underweight.

There are an estimated 2,000 cougars in Washington. Until the 1960s, the state paid hunters a bounty for killing them. Now, it allows 250 to be hunted in 50 designated zones.

While they are sometimes known to kill livestock or pets, and though one even found its way into a park in Seattle in 2009, encounters with people in Washington are rare.

Attacks have become more common as people increasingly encroach on the animals' territory. In North America, there have been about 25 deadly attacks and 95 nonfatal attacks reported in the past century, but more attacks have been reported in the U.S. West and Canada over the past 20 years than in the previous 80, according to Fish and Wildlife.

There's never been a fatal cougar attack in the wild in Oregon, an official said in 2017.

Over 6,000 cougars live in Oregon, according to the Oregon Department of Fish and Wildlife. It's rare for people to see or encounter them, the agency said, but sightings have increased.

What to do if you come across a cougar

- Cougars often will retreat if given the opportunity. Leave the animal a way to escape.

- Stay calm and stand your ground.

- Maintain direct eye contact.

- Pick up children, but do so without bending down or turning your back on the cougar.

- Back away slowly.

- Do not run. Running triggers a chase response in cougars, which could lead to an attack.

- Raise your voice and speak firmly.

- If the cougar seems aggressive, raise your arms to make yourself look larger and clap your hands.

- If in the very unusual event that a cougar attacks you, fight back with rocks, sticks, tools or any items available.
