Authorities in New York have made several arrests in connection with the 2023 death of Robert De Niro’s grandson Leandro Anthony De Niro-Rodriguez, the Drug Enforcement Administration confirms to PEOPLE.

The New York City Chief Medical Examiner later ruled he died from the toxic effects of fentanyl, bromazolam, alprazolam, 7-aminoclonazepam, ketamine and cocaine. It was determined to be an accidental drug overdose death, the ME’s office confirmed to PEOPLE at the time.

Now, more than two years later, authorities in New York say they have made five arrests in connection with Rodriguez’s overdose. All are being charged with death resulting from the sale of narcotics, a DEA official tells PEOPLE.

Rodriguez was the only son of Drena De Niro, the Goodfellas actor’s 56-year-old daughter with his first wife.

She announced his death on Instagram in a moving post.

“I don’t know how to live without you but I’ll try to go on and spread the love and light that you so made me feel in getting to be your mama,” Drena wrote in the post.

Days after Leandro’s death, Drena claimed on Instagram that someone had sold her son “fentanyl laced pills that they knew were laced.”

A woman was arrested later that month in connection with Rodriguez’s death. Sofia H. Marks was accused of selling drugs to the teen. Plea information for Marks was not immediately available.
