A 20-year-old woman has been arrested in New York City in connection with the death of Robert De Niro's grandson, multiple reports said.
Leandro De Niro-Rodriguez — the son of De Niro's adopted daughter, Drena De Niro — was 19 years old when he died.
De Niro-Rodriguez had been found dead in his apartment in downtown Manhattan on July 2, law enforcement sources told the New York Post. She announced her son's death on July 3 and said he died after he was sold pills.
"I'm deeply distressed by the passing of my beloved grandson Leo," De Niro, 79, said in a statement to NBC News earlier this month. "We're greatly appreciative of the condolences from everyone."
An official cause of death has not been released.
Law enforcement sources told ABC News that Sofia Haley Marks has been arrested in connection with De Niro-Rodriguez's death.
Marks' arrest on Thursday was part of a joint investigation by the New York Police Department, the Drug Enforcement Administration, and the Department of Homeland Security, according to the Post.
The DEA and DHS did not immediately respond to requests for comment, and the NYPD said it had no information to provide on the reported arrest.
Marks will appear in federal court on Friday, according to ABC News. It was not immediately clear if Marks had a lawyer.
