Aaron Carter’s cause of death still remains a mystery.

Initial reports claimed he drowned in his bathtub, but his family and ex-fiancée are now rejecting that idea.

There’s evidence to prove drowning was NOT his cause of death.

Jane Carter and Melanie Martin believe their loved one died from a possible drug overdose.

They are still waiting for the coroner’s toxicology report to come back in order to determine what was in Carter’s system when he died.

The Los Angeles County Coroner’s Office say there was no water found in Carter’s lungs.

This is evidence that proves drowning was not a potential cause of death.

The late-singer’s mother wants law enforcement officials to open an investigation into a possible drug deal that went down the night of his death.

Martin found text messages with an unidentified person telling Carter he owed $800 for an unknown substance.
