JUST IN: Leslie Carter Autopsy ‘Inconclusive’….Family Suspects Overdose

An autopsy on Nick Carter‘s sister Leslie was inconclusive, but her family suspects a drug overdose is the culprit.

“There were no visible signs of trauma,” coroner Richard Mackowiak said. “We are awaiting a toxicology report to determine a cause of death … Results of the toxicology test are made public at the discretion of the family.”

But sources tell TMZ Leslie struggled with prescription medication addiction, and they suspect that she may have died of an overdose. Leslie recently moved from Toronto to nearby upstate New York so she can be closer to family and beat her addiction.

Leslie, who died Tuesday at 25, leaves behind her husband Mike and her daughter Alyssa Jane, who was born in April 2011.
