Description:
When a young boy returns home from a late movie, he discovers his mother brutally murdered. With a savage knife attack, no signs of forced entry, and a neighborhood that swears they heard nothing, Sergeant Joe Friday and Ben Romero soon uncover a disturbing trail of jealousy, obsession, and emotional collapse. Their only solid clue: fingerprints on the murder weapon—and a mysterious man known only as Floyd. Originally aired: August 3, 1950.
