Leslie Carter Died of Prescription Drug Overdose, Police Believe

Muscle relaxant, anxiety and bipolar medications found near singer's body.

Though the results of a toxicology test could take several more weeks, an incident report on the death of Leslie Carter
 reveals that the sister of Backstreet Boys member Nick Carter was under the influence of several prescription drugs at the time of her death.

According to ABC News, details from the report compiled by officials who responded to the 911 call from Leslie Carter's family reveal that three drugs were found near her body: one to treat symptoms of schizophrenia and bipolar disorder, a muscle relaxant and an anxiety disorder medication.

Leslie's stepmother, Ginger Carter, told authorities that the onetime singer had a "long history of mental illness and was on medication for her depression" and that she seemed depressed on the morning of January 30. In addition, she fell down in the shower on that morning, after which Ginger helped Leslie lie down in a bed and checked in on her periodically. Later that day, Ginger realized that Leslie, 25, was not breathing and Robert Carter, Leslie's father, tried to perform CPR on her before they called 911.

The incident report also claimed that Ginger Carter appeared to be under the influence of drugs and/or alcohol when authorities responded, exhibiting "slurred speech, pinpoint pupils, glassy eyes and [she] kept falling asleep." Ginger told officials that she had taken "five to six" pills for depression, which was more than her usual dose, "because of Leslie passing away."

In the wake of his sister's death, Nick Carter had promised to keep working and on Thursday night he was back on stage at New York's Irving Plaza for a solo show. In his first public appearance since Leslie's death, Carter put on his standard high-energy show, including original songs from his recent album and covers of U2's "With or Without You" and Rod Stewart's "Do Ya Think I'm Sexy."

E! Online reported that he also took it down a notch when he pulled out an acoustic guitar and spoke for the first time in public about his Leslie. "I never thought I'd ever have to, but I'd like to dedicate this song to my sister," he said with a hitch in his voice. He then performed his song "Falling Down," his eyes welling up with tears as he sang.
