Doubt it will be anything more than a suicide. She got arrested, realized that she traveled across the country for a job she might lose, and made a bad decision. You'd be crazy as a c.o. to try and murder someone on one of those tiers, you've got the cameras, other c.o.'s of all colors around. You've also got to strangle her, plus rig up a crime scene, etc....
At worst, someone might get in trouble for not watching the plastic bag, if they figure out how she got it.
