The club icon was found dead in his downtown New York apartment on Friday, aged 36.
Goldstein's cause of death has yet to be released, but insiders tell People.com that eight undigested OxyContin pills were found in his stomach, as well as a ninth in his mouth -- suggesting his death was a suicide.
A law enforcement source tells People.com, "He wanted to die. He was going unconscious when he took the last one. He didn't even swallow it."
The report adds that crack cocaine and a pipe were found by Goldstein's body.
People.com's insider also alleges that the DJ had barricaded himself in his apartment, placing mirrors against the front door and the door of his bedroom -- where his body was found.
The source explains, "(He) smoked a lot of crack, barricaded the doors and killed himself."
The star's girlfriend Hayley Wood this week blasted claims that he committed suicide because she dumped him, insisting they were still together when he died -- but People.com's source reveals that a Valentine's Day card she gave him back in February was on a coffee table in the living room.
Goldstein will be laid to rest on Thursday.
