Police in the Prince death investigation have interviewed a lawyer who repped 2 of the singer's siblings who claimed Prince abused Percocet and cocaine and they feared he'd "die young."
Mike Padden is an attorney who repped Prince's half sister Lorna and stepbrother Duane in the early 2000s. Padden tells TMZ both Lorna and Duane separately told him Prince regularly abused the drugs. BTW, Duane was very close to Prince and even worked as his bodyguard.
We're told the lawyer contacted the cops and they called him back over the weekend for an interview and he relayed the information about the drugs.
Duane died in 2011 and Lorna passed in 2006, so Padden's information is not up to date. Another very close family member -- who was in touch with Prince 'til the end -- also tells TMZ Prince had used those drugs for many years.
There's another point of view ... we've spoken with several people who were around Prince in the last few years of his life who say they saw no evidence of drug use ... saying Prince was a "health nut."
As we reported, Prince OD'd on Percocet 6 days before he died.
The investigation into his death is ongoing.
