Definitely too short to be human.
#1 Maybe a front or rear pastern if it is a deer. Maybe some kind of digit?
Maybe even a cannon or tuber calsis bone if it is a non-cloven hoofed animal.
#2 Radius or Ulna... looks like right. Part of the forearm... remember that deer to not have rotational ability.
#3 Tibia possible right.
#4 Looks like the same bone as #2.
I am definitely more comfortable with the human anatomy than any non-human mammals... my vote is don't call the cops anytime soon.
