The First 48: Missing Persons

Detectives Selles Morris, Laura Skrip and Jim Corcoran team up to search for a straight "A" college student. They uncover surveillance footage that shows the 19-year-old sophomore walking toward the lakefront, then disappearing. Their around-the-clock search comes to a shocking conclusion. Then, Detectives Morris and Skrip pull double duty: Morris hunts down an alleged gang member who vanished after a drug deal goes bad, putting his own family in danger. Skrip has just minutes to save the life of a woman who threatens to jump from a bridge.

When a caretaker reports her 63-year-old cancer patient missing, Detectives Ayanna Corbin and Mike Cochran learn the woman has left behind a 15-year-old son. Detectives sift through false sightings, deceitful witnesses and a missing mattress.

Detectives Laura Skrip and Joe Struck hunt for a man after his family receives a threat to his life. They must sort through the missing man's troubled family situation and possible drug connections. Next, during a summer of gang violence on Chicago's streets, Detectives Mario Gonzalez and Hector Crespo search for a teenager with a rare sleep disorder. He vanished after getting into a fight with a group of boys. Detectives race to find him before he becomes another casualty.
