ABC News reports that a woman has been arrested in connection with the death of the grandson of actor Robert De Niro. 

A couple of weeks ago it was reported that De Niro's grandson - 19-year-old Leandro Anthony De Niro-Rodriguez - had passed away.

NBC News, at the time, reported:

The New York City Police Department said De Niro-Rodriguez was found unconscious just after 2:20 p.m. Sunday at 55 Wall St. in lower Manhattan. Emergency medical personnel pronounced him dead at the scene, police said.

The death was confirmed by the boy's mother, Drena De Niro, in an Instagram post. She wrote:

My beautiful sweet angel . I have loved you beyond words or description from the moment I felt you in my belly,” she wrote. “You have been my joy my heart and all that was ever pure and real in my life . I wish I was with you right now…. I don’t know how to live without you but I’ll try to go on.

A cause of death was not initially released in the case. But, since then, there have been reports that the death was the result of a drug overdose.

Now, 20-year-old Sophia Haley Marks has been arrested in connection with the death of the 19-year-old. Marks, according to ABC, is allegedly known on the streets as "Percocet Princess."

It is alleged that Marks sold to De Niro's grandson the drugs that led to the boy's death.

U.S. Attorney Damian Williams has released a statement on Marks's arrest.

Williams said:

Last night, my Office, the Southern District of New York, authorized the arrest of Sophia Marks in connection with her distribution of fake oxycodone pills that contained fentanyl. At least one of Marks’s counterfeit pills was purchased and taken by a teenager who subsequently died of a suspected overdose. The arrest was critical because, as we allege, Marks knew the pills could kill, and she continued selling them anyway.

Williams added a statement highlighting the dangers of fentanyl.

"Fentanyl is now the number one killer of Americans between the ages of 18 and 49. More than cancer, car accidents, or gun violence," he said. "It is a law enforcement crisis and a public health crisis. And we are doing everything we can to stop it."

Marks has been charged with one count of distributing and possessing with intent to distribute fentanyl and alprazolam.

She has also been charged with two counts of distributing and possessing with intent to distribute fentanyl.

These charges carry with them a maximum penalty of 60 years of imprisonment.
