I wonder if she had parked her car, gotten out and started walking to meet the carpool when she realized she'd forgotten her badge. I know that I am always double checking my pockets/purse after I first get out of my car to make sure I have my keys, phone, work id, etc. She might have stopped to text her friend then, mid-walk, to say she was going to be late and then never made it back to her car. Someone stopped and distracted by using their phone would make for an easy target. As for what happened after that, who knows, dragged into the woods and carried out later? Put into a trunk or back seat of another car and driven away? No matter what, it's worrisome that there's so little to go on.
