We can definitively say that they had sex outside when she was 17 and he was 21. But since the DA didn't charge him with what appears to be statutory rape, there must have been evidence she told people she was 18 and it was consensual. We can also definitively say that none of the videos of her having sex with multiple men inside the house involved Araiza, therefore there is zero proof he was involved in what went on inside the house.
