In the quiet community of Collinsville, Oklahoma, a family was left with unending questions following the disappearance of 36-year-old Male Thai Yang. Around the end of June 2019, Thai was last seen by his relatives at his home. The following morning, they discovered he was gone. This was not the first time Thai had gone out for a walk, a common pastime for him, but the length of this absence was alarming and out of character. Compounding the family's concern was Thai's gentle nature; he has a mental disability and the cognitive capacity of a young child, which can make communication with others difficult. His case is considered that of an endangered missing person because of his vulnerability. The evening he was last seen, there were no signs of anything amiss. When Thai left his home, he had his wallet, which contained his Oklahoma identification card and a medical card. He also had his house keys and a cigarette lighter. He did not take his cell phone or car keys, suggesting to his family that he had intended to return as he always had before. He was thought to be wearing an oversized hooded sweatshirt, jeans, and sneakers. Thai had a preference for wearing clothing that was large on his 5-foot-5-inch, slender frame. His family reported him missing to the Collinsville Police Department, initiating a search for the beloved son and brother. As days turned into weeks and years, the search for Thai continued, though few details about his potential whereabouts have ever emerged. His family fears that due to his condition, he may have become lost or confused and would be hesitant to speak with anyone he did not know. He might have sought out food or a place for shelter. The overview of this case is that of a vulnerable adult who seemingly vanished from the safety of his home in Collinsville. Thai's habit of taking walks turned into a mystery that has left his loved ones without answers. He left with only a few personal items, and with no clear indication of where he was headed, the circumstances of what happened to him after he walked away from his home remain unknown.
