Susan,
My son is in the same boat as your grandson, he is awaiting sentencing on 2/6/16. The girl lied about her age, afraid of prison he accepted a plea deal for 1 count of carnal knowledge. He will begin registering as a sex offender in Feb. I have been sick about this. He was a senior in high school when this happened. I wish there were laws to protect my son/your grandson. They are still children. My son was not a predator, he did seek out someone, he did not rape her. He believe her age was what she stated. This law is not meant our family members who are really victims themselves.
