Lyntell Washington, a 40-year-old teacher who was seven months pregnant, disappeared from Baton Rouge, Louisiana, and was reported missing on June 9, 2016. Her three-year-old daughter was found wandering alone in a parking lot near Washington’s car, which contained blood. A week later Washington’s badly decomposed body was found in a ditch in Iberville Parish; an autopsy confirmed a single gunshot wound to the head.

Investigators focused on Robert Marks, a 39-year-old married assistant principal at the same school, after learning the two were having an affair and Washington was pregnant with Marks’ child. A coworker said Washington had threatened to tell Marks’ wife. The child told investigators that Mr. Robbie hurt her mother, heard a bang, and saw her mother shaking. Cell phone records placed both phones in the Ramah area, about 25 miles from Baton Rouge, on the night Washington disappeared.

Marks was arrested and charged; following the discovery of Washington’s body the charges were upgraded to first-degree murder and first-degree feticide. Later developments have occurred; did anyone in Baton Rouge know Lyntell, her routine, or see her car the night she vanished?
