The day after 25-year-old Leslie Carter was found dead in her upstate New York home, the Chautauqua County Coroner's Office announced that an autopsy was inconclusive and that his office is awaiting toxicology tests to determine what [article id="1678313"]caused the death of[/article]
the onetime singer and younger sister of Backstreet Boys star Nick Carter.

E! Online reported that coroner Richard Mackowiak said there were no visible signs of trauma to Leslie Carter's body and that toxicology test results are pending. "The body has been released to the family," he said on Wednesday. "Results of the toxicology test are made public at the discretion of the family."

It could take four to six weeks for those results to surface.

TMZ speculated on Wednesday that prescription medications could have played a role in Carter's death. Citing unnamed sources close to Leslie, she had recently moved from Canada to upstate New York to live with family members as she struggled with prescription drug issues.

She leaves behind her husband, Mike, and daughter, Alyssa Jane Ashton, born last April. While her career had always been on a lower profile than her famous siblings, who include Backstreet Boys member Nick as well as singer Aaron Carter, she had attempted several times to jumpstart her own singing career.

Leslie recorded a never-released debut album under the Dreamworks Records label back in 1999, at the height of BSB fandom. Two years later, her song "Like Wow!" appeared on the soundtrack for the first "Shrek" movie. After several stops and starts to her music career, she might best be remembered for appearing alongside her siblings on the E! reality show "House of Carters," which aired on the network in 2006.
