AceShowbiz - Bobbi Kristina Brown's former boyfriend, Nick Gordon, died of a heroin overdose.
Autopsy and toxicology reports have confirmed his cardiac arrest was brought on by drugs.
According to TMZ sources, medics also found Narcan in his system, which is a drug used to reverse the effects of an overdose.
Gordon spent seven hours in the hospital before he died over the holidays. His brother confirmed the news on New Year's Day (January 1), suggesting he'd died after suffering an overdose.
Sources claim he never recovered from the death of his girlfriend, Bobbi Kristina, in 2015. She overdosed in a bathtub at the couple's home and died several months later.
Gordon was found legally liable for her death but he was never officially charged.
