Hang her, definitely. And, if it isn't asking too much, make a long series. I always find the drawn out hangings/stranglings to be the best, as if I can follow along with the pictures and play back the event in my head watching her dance longer.
May be a more believable scenario- overpowerd by her new tennis couch and a few male students on a tennis court of a private club after ours. Humiliation - forced to be naked ball fetcer - also tied to the net in defirent positions showing her genitals off - even a tennis racket holder with het vagina and anus to hold te rackets. and I'm sure it can end up in rape and somehow enslavement.
What about her riding a dildo mounted on a chair or bench, unaware of the device below the seat, which might be, for example, a gun which will make the dildo "fire its load" in a very literal sense. It might also be a spear or something like that.
Chased, kidnaped, bounded, humiliated, tortured and beated up, raped (except DA forbid it), restrained in long-term bondage (long-term immobility, inescapable bondage)(in presence or not of others victims) and finally assistant of her kidnaper in a Stockholm syndrome, and eventually her own dungeon mistress. (very close to a "BDSM/Snuff Saw", my bad, it wasn't my initial think) ?
