Dateline NBC “The Alibi” December 27 2025 Recap & Preview

NBC’s Dateline presents “The Alibi,” a compelling Weekend Mystery reported by Andrea Canning, airing Saturday, December 27, 2025, at 9 p.m. ET. The episode explores the chilling murder of Karlyn Ramirez, a 24-year-old Army specialist, wife, and mother, whose life was tragically cut short at her Maryland home.

When Karlyn was found shot to death in August 2015, cradling her baby daughter who miraculously survived the attack, the case shocked the military community at Fort Meade and left investigators searching for answers. With no signs of forced entry and few immediate leads, detectives turned their attention to those closest to her, including her estranged husband, Maliek Kearney, also an Army soldier.

As Dateline unpacks the timeline of events and the investigation that followed, viewers learn how a trail of digital evidence and cell phone data eventually dismantled the suspect’s carefully constructed alibi. Prosecutors alleged that Kearney drove hundreds of miles from South Carolina to commit the murder, then returned to establish his whereabouts elsewhere.

Andrea Canning speaks with law enforcement officials, loved ones, and those involved in solving the case. The episode details the years-long journey to justice, culminating in a trial that brought closure to Karlyn’s family and raised questions about domestic violence and manipulation within military relationships.

With exclusive interviews and courtroom footage, “The Alibi” provides a detailed look at a disturbing murder driven by control, jealousy, and revenge — and the determination of investigators to uncover the truth behind the uniform.
