In video 16, she eats her sandwich, wipes her mouth with the tissue, puts it in the trash. Grabs a napkins for her hands. Almost puts it in the trash. Retrieves that tissue back out the trash and puts it in her lap. I no longer see it after that.
Was she afraid someone would get her DNA off the tissue cause she wiped her mouth? They told her they already had it, but police are allowed to lie. Maybe she's trying not to take chances. Was this the paper she was asked to give back? Nevermind. I see she's pocketing notebook paper. What of the tissue?
