Richard Halliday, a 21-year-old Army private, was last seen on July 23, 2020, at Fort Bliss in El Paso, Texas. He was initially classified as Absent Without Leave after failing to report for duty; later reviews corrected the last known sighting to July 23, which shifted the timeline of his disappearance. At the time he went missing he was reportedly on restricted movement and under escort but managed to evade those minders.

Extensive searches by the U.S. Army Criminal Investigation Division, local law enforcement and federal partners were conducted at Fort Bliss and nearby areas, but Halliday has not been found. His family in Florida did not learn of his absence until late August after not hearing from him for several weeks, prompting questions about the communication breakdown. The Army later elevated his status to Missing and offered a reward for information.

No definitive leads have emerged and the case remains unresolved. If anyone saw Richard at or near Fort Bliss in late July 2020 or has information about his movements after July 23, please come forward.
