Daughter who is 17 climbed out of her window and met a man 20 and engaged in sexual intercourse. I woke to her empty bed because she fell asleep while gone. I took her cell phone and computer and found out 2 days later he bought a prepaid cell and gave it to her. When I got the phone from her it had him asking her to send nude pictures which she did, and ask for a video next time they get together. He also sent her picks of his genitals with rude sexual comments. I spoke to this man before this and warned him about this type of contact with my daughter and he apparently doesn't believe me. Do I have any grounds and are they likely to convict if illegal?
