It sure seems like he should be charged.
The authorities in North Carolina are getting sworn statements from her friends at the time to verify she discussed it back then with them.
Apparently there’s either email or some type of texting communication back then (saved some way) that verifies she told them then what happened with details.
But all speculation at this point.
My guess is the woman will pursue it and rape charges are coming. No way she’d hire a law firm and have friends talking to “authorities” unless she was filing a formal complaint.
