CBS’s 48 Hours presents a powerful and emotional new episode titled Kimberly Langwell’s Hidden Grave, airing Saturday, April 11, 2026, at 10:00 PM ET/PT. Reported by Peter Van Sant, the broadcast revisits a decades-old mystery from Beaumont, Texas, where a mother’s sudden disappearance left her family searching for answers for more than 20 years.

Kimberly Langwell vanished after failing to return home from work, leaving behind her daughter, Tiffani McInnis, who was just a teenager at the time. With few clues and no clear suspects, the case went cold, forcing Tiffani to grow up without knowing what had happened to her mother. Despite the passage of time, hope never fully faded.

Years later, new information reached investigators, reigniting interest in the case. Detectives began reexamining old evidence and following fresh leads, eventually uncovering a secret grave that held the key to solving the mystery. The discovery brought long-awaited answers and revealed the truth behind Kimberly’s disappearance.

The episode features interviews with Tiffani McInnis, who shares her emotional journey and the impact of decades without closure. Beaumont Police investigators, including Detective Heather Wilson, former detective Joe Ball, Lieutenant Mitch Sliger, and Detective Jesus Tamayo, explain how the case was revived and solved. Prosecutor Luke Nichols and Texas EquuSearch founder Tim Miller also provide insight into the investigation and recovery efforts.

Kimberly Langwell’s Hidden Grave is a story of persistence, loss, and the determination to uncover the truth, no matter how much time has passed. The episode airs Saturday night on CBS and streams on Paramount+.
