The animal was found over the weekend dead in a yard, several residents said.
The coyote had first been spotted in mid-August. wandering neighborhoods in Echo Park and Silver Lake.
It had a red dog toy lodged in its jaw, and it struggled to eat and drink.
Video taken by one neighbor shows the coyote with what appears to be a red Kong toy lodged around its bottom jaw trying to drink from a water fountain and struggling to get water into its mouth.
"He had this red object in his mouth," said resident George Scheideman. "I thought he was just carrying it around. I looked more closely. He was trying to get it off, couldn't get it off. Looked very uncomfortable."
Local residents had notified city animal control and private rescue groups to try to help the coyote, but they were unable to locate the animal in time.
