history: I think I have a coyote or wolf running around my area. I think it killed a little beaver that lived near the creek  near my house. I saw a wolf or coyote in my yard a while back and I think it killed a little beaver that lived in the creek  for years behind my house.
current: That must have been amazing to see!  Did you try to scare it away or just watch it?  Be careful since it sounds like it may be dangerous.
next: No I didn't see it happen, there was a piece of a dead animal that looked like the beaver in my yard, just the mouth and eyes were left. ugh..
