The Western Coyote is a small critter and lives a solitary lifestyle.
The Eastern Coyote is actually believed to be a hybrid between the western coyote and the eastern timber wolf. It gets larger and can form form packs. Its dangerous - obviously. People who hike or travel in areas where dangerous animals are found, should be allowed to be armed, or should be accompanied by another individual who is capable of handling a weapon.
This is really a horrible tragedy which lever should have happened.
Here is a good site on coyotes.

Western Coyotes are definitely smaller than 45lb. We have them around our house all the time.
I live in the high-desert area of Central Oregon and I can assure you that they do “pack-up” and the one’s around here are about the size of a medium-sized German Shepherd.
I hear ‘em most every night and catch glimpses of them a couple of times a year during the day. The problem here w/solitary hikers/bikers/climbers is Mountain Lions, not coyotes.

You’ve been misinformed, all coyotes run in packs. Evenings and mornings you can hear a chorus of them near my house. Most that I have seen are about the size of a medium shepard.
