Wildlife officials had been on the hunt for the snake -- which can grow up to seven feet long and packs enough venom to kill someone in an hour -- since it had bitten a dog on Monday. It was the first time the snake had been seen since the dog was bitten.
The snake was found along a fence by a woman driving by, not too far from where it was first spotted.
The snake will stay at the Los Angeles County Department of Animal Care and Control until officials from the Los Angeles Zoo can pick it up and look at it.
Whoever owns the cobra has not yet come forward.
