I haven't seen an answer for this yet. Is he being charged as a sex offender for having sex with a minor?
According to Louisiana felony laws, it is not against the law for a 16 yr old to have consensual sex with an 18 yr old. If the baby was conceived after he turned 19 then he can be charged. If he was 18 and she was 15, that is also a felony.
Does he still live in Louisiana, or do they live in Los Angeles now? I don't know what the ages are for consensual sex there.
