I don’t love Don Henley as a person, but it might be hard to determine what happened 40 years ago.
It happened. The record gurus covered it up.
Indeed.
The underage prostitute was there, doing drugs at Henley's house (she was arrested for prostitution). That part isn't in question, though she didn't "OD". This is the incident Henley wrote the song "Dirty Laundry" about.
Henley plead no contest to "contributing to the delinquency of a minor", paid a fine and probation. This isn't about that case, but some guys who ripped Henley off getting to use this incident to impeach him as a witness. They are hoping to embarrass Henley to force a settlement. Henley is worth at least $200M-$250M and still touring with the Eagles at large venues. This is probably personal for him to pursue it this far.
Worked for E. Jean Carroll. She couldn't even remember what year it happened (totally denying Trump the opportunity to present an alibi) and still walked away with millions that she'll never see a penny of.
