Maybe what they were doing themselves. From Henley's Wiki page:
'Henley called paramedics to his home on November 21, 1980, where a 16-year-old girl was found naked and claiming she had overdosed on quaaludes and cocaine. She was arrested for prostitution, while a 15-year-old girl found in the house was arrested for being under the influence of drugs.'
16 and a 15 year old?
I didnt know about the girls. Yeah, changes things a lot.
