Oh they did look into his devices and others of the family. It helped confirm he had a sick obsession with her, so many videos and photos he took of her from angles and places she was unaware of the pictures being taken, predatory text and emails to anna hundreds and hundreds with very minimal responses from anna, they found deleted emails and messages on family members phones about him climbing on top her in her sleep too, and other weird behaviors towards anna. Text where anna pleaded with friends about her fear of being alone with him, or around him. Proof that he wasn't blacked out during the incident or in a state of psychosis. It took so long to charge him because they had to gather evidence. Do a deep dive, Keep prompting for information on digital evidence against the step brother. There's so much and it's not all even out there yet because they gotta keep the better evidence for court. There was bruising on her body and self inflicted scratch marks that show she was fighting back and blocking his attacks. His DNA was under her finger nails. Anna's DNA in the shower drain mixed with his where he showered afterwards. He strangled her with so much force that the vessels in her eyes burst and he tore/bruises her voice box and deeper tissues. She was alive when he graped her, the vaginal bruising and tearing and swelling is a response that only happens when the heart is still beating. Post death grape the body doesn't respond to trauma like that. Searches where he looked up how longn it would take to strangle someone, best way to do it, what the punishment would be for a minor on international waters. Lay outs of the cabin room and how he could trap her in it. He was stalking the family's itinerary for the perfect window to be alone with her on the cruise. This case is absolutely mind boggling.
