Missing: Stepha Henry

Police have tracked cell phone signals and examined abandoned cars, yet there's no trace of a woman who vanished last month after going to a Florida night club.

Miami-Dade County police have said they don't know whether foul play was involved in Stepha Henry's disappearance, but family members think something happened to the 22-year-old honors graduate of John Jay College of Criminal Justice.

Henry was visiting relatives in the area with her 16-year-old sister and made plans for a friend's brother-in-law to pick her up on May 29, her aunt Daffodil Samuel said Sunday at the family's home in Brooklyn.

Relatives saw Henry get into a black sedan with a man. There is video of Henry at a Sunrise nightclub and police have said they have questioned a man who told them he left her at the nightspot.
