Case Description

Any updates on this case? Let us know!
Summary based on the NamUs case record (MP52478) and 7 other sources
Matthew Hallman, 51, was last seen on July 22, 2011, in Greenville, Texas. Hallman, an executive with L-3 Communications, had been at a property he and his wife owned in the rural southern part of Greenville, performing routine maintenance. His last communication was a text message sent to his wife on July 23, 2011, indicating he had completed some tasks and would return to their Rockwall residence soon. However, he never made it home, and no one has heard from him since.

Investigators have found few clues in Hallman’s disappearance, and despite ongoing efforts, the case remains unsolved. No leads or significant evidence have emerged over the years, leaving his family and local authorities frustrated. Both the Hunt County Sheriff's Office and the Texas Rangers have been involved in the investigation, but without new information, the case has remained cold. His family continues to seek answers and hopes that public attention will bring new information to light.
