Creepy old man stalking Allyssa

No this isn't a joke. This is the second time he has asked if he can have Allyssa. This time he also asked Allyssa if she wanted to go home with him. The police said that because she is too young to talk they can't charge him with inticing a minor, but I am supposed to speak with a detective on Friday to find put what I can do next time he finds us.
