The body of 13-year-old Minnie Soriano is found by a homeless man in a dumpster. The girl has been sex abused and strangled. Now after 22 years, 49-year-old Joseph Martinez has been arrested. Officials allege that Martinez, who teaches astronomy on the street, knew Soriano because he lived in her building. The teen also had an interest in astronomy and wanted to be an astronaut. Police say familial DNA technology pointed to Martinez. This is the first time the technology has been used in New York City.
