Okay, got 3 snakes from my facebook friends. Been following these threads so I'm working my identification skills.
First is the post "my husband killed a cottonmouth on our steps". Yellow jaw that looks segmented, head not the hard arrow shape, markings clear and not "faded", might have even flared out its neck before they lopped its head off... and his eyes look kinda friendly. I guess maybe Hognose with that pattern and being kinda fat?
Next, no murder luckily... but snakes caught in minnow trap so still dead. Poster said "they stunk having been in the trap a few days so I tossed them quickly, but don't think they were moccasins". All I can make out is the yellow belly and some striping so I'd guess the banded water snake?
