Robert De Niro’s grandson Leandro De Niro Rodriguez‘s cause of death has been revealed.
The 19-year-old died from a “toxic” combination of illicit drugs, the New York City Medical Examiner told Page Six Tuesday.
According to the autopsy results, Leandro had fentanyl, bromazolam, alprazolam, 7-aminoclonazepam, ketamine and cocaine in his system at the time of his death, which has been ruled an “accident.”
Drena De Niro announced on July 2 that her son, whom she shared with graffiti artist Carlos Rodriguez (aka Mare139), had died.
“You have been my joy my heart and all that was ever pure and real in my life,” she wrote in an Instagram tribute.
“I wish I was with you right now. I wish I was with you. I don’t know how to live without you.”
The Daredevil Films founder wrote that she wished her “love alone could have saved” her son.
“I’m so sorry my baby,” she continued. “Rest in Peace and Eternal Paradise my darling boy.”
Meanwhile, Carlos, whom Drena tagged in her post, shared a photo of a black square on his own account — and left the caption section blank.
Law enforcement sources told TMZ that Leandro was found dead sitting in a chair by a friend who was checking in on him after not having heard from him in a few days.
