Among them is the most recent episode, Season 32's finale, “The Shadow in the Window." The case centers on the mysterious death of 35-year-old mother, Nada Huranieh. “None of it felt real, like none of it felt real,” her daughter, Aya Altantaw, who was just a teen when she found her mom not moving and lying face-up on the patio, told Dateline. According to the episode's description, “What initially seems like a fatal accident reveals itself to be something much more disturbing."

Also available to watch is another recent episode, Season 32's “The Day Akia Disappeared,” about pregnant Baltimore woman Akia Eggleston, who vanished in May of 2017, right before her own baby shower. "She was eight months pregnant, so, to just disappear on her own — highly unlikely," Baltimore Police Department Detective Jill Beauregard told Dateline. Investigators working on the case uncovered details that “Akia’s family knew nothing about," according to Dateline.
