Fifteen-year-old Thomas Medlin was last seen Friday, January 9, 2026, leaving the Stony Brook School in Stony Brook, New York, about 3:30 p.m. He ran to the Stony Brook LIRR station and is believed to have taken a train to Manhattan, where he was seen at Grand Central Terminal around 5:30 p.m. His family has had no contact with him since that evening, and his mother Eva Yan says this behavior is highly out of character.

Detectives say Thomas may have traveled to meet someone he had been communicating with on the online gaming platform Roblox. Police traced his last known locations to Cherry and Rutgers streets in Lower Manhattan and later near Sands and Jay streets in Brooklyn. He is described as a white male, 5 feet 4 inches, 130 pounds, wearing a black jacket with red stripes, dark sweatpants with white stripes, a black backpack, and glasses when last seen.

The Suffolk County Police Fourth Squad and the National Center for Missing & Exploited Children are handling the case. If anyone has information about Thomas Medlin’s whereabouts, please contact the Suffolk County Police Fourth Squad Detectives at 631-854-8452 or call 911.
