Male bodies being found in Hudson River

We're digging deeper into the story of young men disappearing and later being found dead in the Hudson River.

Anthony Urena, 23, was one of those men. We spoke to his mother, Judith Lopez, in Manhattan.

Around 5 a.m. Nov. 14, Urena was seen on surveillance footage staggering down a sidewalk in Hoboken. His body was pulled from the Hudson River on Christmas Day.

Although police do not suspect foul play, Lopez believes her son may have been drugged.
