COLFAX -- Authorities plan to perform a necropsy on a mountain lion that was shot and killed by a California Fish and Wildlife warden in Placer County over the weekend.

The warden had gone to the area near Colfax on Sunday to post signs warning hikers about a mountain lion sighting there a day earlier when he noticed the animal.

Fish and wildlife spokesman Mark Michilizzi tells the Sacramento Bee (http://bit.ly/XsXSyR) the mountain lion appeared prepared to pounce on the warden, who then shot and killed it.

Michilizzi called the warden's actions appropriate, saying the mountain lion was a risk to the warden and the public.

A necropsy is planned to try to help officials determine what may have prompted the animal's behavior. Mountain lions rarely attack humans.
