Police in the US believe that Sylvester Stallone's son Sage was a drug dealer rather than an addict, TMZ reports.
At 85kg and 170cm, 36-year-old Stallone was too heavy to be a drug addict, a law enforcement source told the entertainment website.
"He was pudgy, and drug addicts are almost always rail thin," they said.
Stallone had enough Hydrocodone bottles in his home to hold 30,000 pills but all were empty, leading Los Angeles detectives to believe he was dealing.
The robbery-homicide division is now investigating Stallone's death after his body was found in his Los Angeles home last Friday.
His attorney told People magazine that Stallone did not even drink.
"There has been no indication that there was anything wrong in his life."
