It has been more than 100 days since Pvt. Richard Halliday, a soldier who went missing from Fort Bliss this summer, was last seen.
"We will climb many mountains and follow any credible lead to find Richard," Halliday's family said on Friday in a statement through the 1st Armored Division, according to Stars and Stripes. "We love him, miss him, and want him to have a future."
Halliday, 21, was last seen on July 23 leaving his barracks room at Fort Bliss.
Halliday is 5 feet 9 inches tall and 162 pounds and was wearing gray or turquoise cargo shorts, a gray t-shirt, and a gray zip-up hoodie, and dark gray running shoes with red, white, and yellow paint stains on them.
He is assigned to D Battery, 1-43rd Air Defense Artillery Regiment, 11th Air Defense Artillery Brigade, 32nd Army Air Missile Defense Command.
Halliday's mother, Patricia, said in October that they suspect foul play in his disappearance, though the Army Criminal Investigation Command (CID) has said they do not.
Army CID is leading the investigation into Halliday's disappearance alongside local authorities, Stars and Stripes reported, though it is not a criminal investigation.
His family's search for him extended into Juárez, Mexico, at the beginning of October.
Searches have also been conducted into Franklin Mountain National Park; according to Stars and Stripes, human remains canine units were brought out to conduct searches on Oct. 12 and 20.
Anyone with information is encouraged to contact the Fort Bliss CID office at 915-568-1700, the Fort Bliss military police at 915-744-1237, or their local law enforcement.
