His parents said he vanished suddenly and without a trace.
“He got separated from his best friend during the concert while they were walking away to go sit down and rest for while. They were going through a big crowd of people. [His friend said] he turned around and Justin was gone, just like that,” said his father, John Walker, per KENS5.
Walker is a white male standing 5 feet 9 inches tall. He has brown hair and green eyes. He weighs 175 pounds and was last seen sporting a navy blue tribal shirt with dark shorts, Nike shoes, and a black hat.
Volunteers have been scouring the area around the park searching for any sign of the missing man.
Meanwhile, his parents are pleading for anyone with any tips to come forward.
“We want our son to come home, and if anybody has any information, [we will take it] no questions asked,” John Walker told KENS5. “We just want to know where our boy is, and we just want to get him home.”
Those with information regarding Walker’s whereabouts are being urged to call (956) 761- 5283.
