The Fayette County Coroner's Office said Monday that Melissa Kline-Smiley, 37, of Lexington, had heroin and several other drugs in her system when she collapsed and died last summer.
Her manner of death still hadn't been determined, but could be released later this week, according to the coroner's office.
Investigators have not ruled whether her death was an accident or a homicide.
Lexington Police said Kline-Smiley collapsed July 25th while working on a painting job at Fillies Gentleman's Club on Winchester Road.
Investigators said the man she was working with at the strip club, Clyde Wesley Sexton, 71, performed various sexual acts on her while she was unconscious.
Investigators said there was surveillance video of the reported sexual abuse.
Police said no one called for help until 20-to-30 minutes after Kline-Smiley collapsed.
She ended up on life support at UK Hospital for four days before being pronounced dead on July 29th.
Police charged Sexton with first-degree sexual abuse. He pleaded not guilty at his arraignment in Fayette District Court.
He case was eventually sent to a Fayette County grand jury.
