"Nothing could have been further from the truth. I would give my life for either one of them. I'd trade places right now," Stern told Fox News' Greta Van Susteren last year.
In a 2007 interview with CNN's Larry King, Stern said that some prescriptions for Smith were put in his name in order to protect Smith's privacy. "But they were through doctors trying to look out for her health," he said.
Brown said there was "clear evidence" that Smith was addicted to drugs. He did not say what the motive may have been for the alleged crimes, but said, "These people were caught up in being in a relationship and being around this celebrity, Anna Nicole Smith."
"There's a certain psychic gain to be a part of the glitz and celebrity and power. There's a lot of money floating around. A lot of high life," he said.
Speculation swirled around Stern as the last years of Smith's tumultuous life played out in public. Smith's mother, from whom she had been estranged, publicly accused Stern of being involved in her daughter's death, which he has denied.
Stern also claimed to be the father of Smith's daughter, Dannielynn, sparking a protracted paternity dispute. Stern dropped his claim after a DNA test revealed that Smith's former boyfriend, Larry Birkhead, was the father.
Smith was buried in the Bahamas next to the grave of her son.
