^^^^^ I agree. Possible co-worker trying to smear her reputation OR a love interest from OM1 or OM3??? I haven't read your whole sitch.
I would let it drop.
If you already know what is this going to do for you??? Someone is hoping to rile you up - their motivation is currently unknown but I wouldn't step in that river of stench if I were you.
Good Luck. That would certainly twist my head up for sure and not in a good way.
