NEW YORK (CNN) — Tests on a $20 bill found at the Lower Manhattan apartment where "Brokeback Mountain" actor Heath Ledger died yielded no drug residue, New York Deputy Police Commissioner Paul Browne said.

The bill was collected to see whether it had been used to snort illegal drugs because of the way it was folded, New York Police Commissioner Ray Kelly said earlier. The Academy Award-nominated actor was found dead Tuesday. He was 28.

An autopsy Wednesday morning was inconclusive, and a cause-of-death determination will take 10 to 14 days, a medical examiner’s spokeswoman said.

"There were no illegal drugs found" in the apartment, Kelly said on Wednesday. He said there were prescription drugs, in their bottles, not strewn around as previously reported.

Two law enforcement officials who asked not to be named said six types of prescription drugs, including an antihistamine and pills to treat anxiety and insomnia, were found in the apartment, according to The Associated Press. A publicist for Ledger told CNN Thursday that the actor was suffering from the flu and had been prescribed antibiotics during recent filming for "The Imaginarium of Doctor Parnassus" in London. New details are emerging about the moments before and after Ledger’s death.

Brad Renfro, the former child star whose later career was hampered by drug and alcohol problems, has been found dead at his Los Angeles home. He was 25.According to reports, Renfro’s body was discovered at 9am yesterday. The cause of death has yet to be determined, although the actor is believed to have been out drinking with friends the night before his death. "He was working hard on his sobriety," Renfro’s lawyer Richard Kaplan said yesterday. "He was doing well. He was a nice person."

Raised by his grandmother in Knoxville, Tennessee, Renfro was plucked from obscurity at the age of 12 to star alongside Susan Sarandon and Tommy Lee Jones in the 1994 blockbuster The Client, based on the bestseller by John Grisham. The following year he won the Hollywood Reporter’s "young star" award. Renfro went on to enjoy a fitfully successful acting career with a starring role in Bryan Singer’s Apt Pupil and supporting turns in the likes of Sleepers, Bully and Ghost World. He recently completed work on the Bret Easton Ellis adaptation The Informers, in which he stars alongside Winona Ryder and Tommy Lee Jones. But Renfro’s career was often overshadowed by his off-screen trials. In May 2006 he served 10 days in jail after attempting to buy heroin from an undercover police officer in LA’s Skid Row area. More recently, Renfro claimed he was making efforts to stay clean. "I’m tired of paying the consequences," he said.
