Sofia Haley Marks was arrested in New York City on Thursday in connection with the overdose death of actor Robert De Niro's grandson, Leandro Anthony De Niro-Rodriguez. Marks is expected to face federal drug charges in a Manhattan federal court on Friday. The death of Leandro De Niro-Rodriguez has highlighted the dangers of drug abuse and the need for more effective prevention and treatment programs, and it is hoped that Marks' arrest will be a step towards curbing the illegal drug trade in the city.
