How do you know? There could be all sorts of evidence. What was their relationship? If they hated each other, it’s a pretty good bet she wouldn’t have consented no matter how drunk she was.

We don’t know what kind of evidence there may or may not be. Trying to prove innocence or guilt based on a newspaper account is pointless.
