A autopsy has concluded there was no marijuana in the body of slain Fifth Avenue millionaire Linda Stein, The Post has learned.
The revelation further undermines the confession of her personal assistant, Natavia Lowery, that she murdered the “Realtor to the stars” in a fit of anger after Stein blew pot smoke in her face, sources told The Post.
Lowery, 26, has admitted to shattering Stein’s skull with a yoga bar in a fit of rage, claiming Stein – who had a reputation as a cranky boss – hurled racial slurs at her and then repeatedly blew blasts of marijuana smoke at her even after she begged her to stop because it was making her nauseous.
But sources say final toxicological tests on Stein completed last week showed no traces of marijuana in her system – putting to rest suggestions Stein had been recently using pot to ease her pain while battling cancer.
Cops also did not find any marijuana ashes near her body.
The medical examiner’s finding fuels the evolving theory of prosecutors and NYPD investigators that Lowery had been looting her boss’ bank and credit-card accounts and that she killed her when Stein discovered the thievery.
“There would be some evidence of the marijuana if she had smoked it,” a forensic expert said, “even traces that had been metabolized for days and days.”
The Post reported last month that Stein’s bank accounts and American Express card showed evidence that Lowery – who had a previous arrest for identity fraud – had stolen tens of thousands of dollars from Stein.
There is even bank surveillance video of Lowery posing as Stein, a punk-rock pioneer who once managed the Ramones.
Lowery’s lawyer, Ron Kuby, yesterday insisted cops coerced Lowery into a false confession.
“The police were able to tell her the things they knew, and she repeated those things back,” he said. “She made things up to get out of the interrogation room. She made up the marijuana smoke. She made up the yoga stick. She made up the killing to get out of the interrogation room.
“The only way to get out was to confess,” he said. “If they had kept her another hour longer, she would have told them the hiding place of Osama bin Laden.”
Stein’s body was discovered lying in a pool of blood in her penthouse apartment last October on a day when the only other person in the home was Lowery.
Just days after the murder, Lowery used Stein’s cards and bought herself tickets to see her boyfriend in Virginia Beach and even pretended to be Stein to try to open more accounts, prosecutors have disclosed.
Lowery, who is pregnant, is being held without bail.
