What do I do if I think someone is sexually soliciting my child online?

First and foremost separate your child from the computer and contact your local police department to let them investigate. If at all possible leave the computer in the state in which you found it so any responding officer will have the ability to see what you saw. If you log out of a site chat logs may be deleted. If they are deleted they can be very difficult to recover – if it is even possible to recover them. There may be other evidence on your computer at the time that will be harder to find once you log out and/or shut down the computer.
