The First 48 Presents Critical Minutes

In Memphis, the tragic murder of 6 people in the same house on Lester Street tears a family apart. In Tulsa, the strange disappearance of a former Navy vet finally provides answers after almost 2 years. And in Atlanta, the brutal shooting of a young engaged couple on the side of the road haunts investigators.

In Tulsa, a key witness denies knowing anything about a brutal homicide until confronted with evidence that proves otherwise. In Dallas, a suspect shocks detectives with a confession they didn't see coming. In Atlanta, Detective Quinn has an uphill battle in the interview room with a suspect who appears to be targeting and killing homeless people.

A confrontation turns deadly in Memphis, Tenn.; in Cincinnati, a single mother is torn between work and home; in Tulsa, Okla., a family dispute takes a dark turn; in Atlanta, an interrogation room interview turns emotional.

Three cases from The First 48 that feature families enveloped in personal tragedies. In New Orleans, two cousins have a deadly fight, in Memphis, a young couple disappear and their uncle's home holds a clue, and in Dallas, a woman brutally turns on her sister-in-law.

Three different approaches to suspect interviews are featured from The First 48. First, detectives in Cleveland sit down with friends and the suspect in the murder of a young mother, then the boyfriend of a missing woman is questioned in Harris County with hopes of finding the woman alive, and detectives in Memphis change strategy in an effort to get their murder suspect to talk.

Three cases from The First 48 where things get out of control in a heated moment. In Birmingham, a man's body is found burned after an argument with a friend; in New Orleans, a man with cancer gets a ride home that ends in his murder; and in Tulsa, a man visiting his son is killed in a jealous rage.
