No one can accurately recall details from that long ago.
From the link provided by the OP this is whole lot more than a single he said/she said incident between adults.
Taken out of the house at 16, on the road with a famous music star for the next three years, late term abortion at 17 or 18. I imagine she would have a clear memory of what transpired.
Certainly not right, what can be proven beyond a reasonable doubt in court pertaining to statutory rape at this point is something else entirely.
I believe the burden of proof in Civil Court is lower. I wish that woman success in this endeavor, Tyler can afford it, time to pay the piper.
