This case reminds me of the Hassani Campbell case. He was 5 y/o and had cerebral palsy and wore leg braces. His foster father said he left the boy at the back door of the business where his aunt worked and went around to the front door to let the aunt know the boy was there. By the time they made it back to the back door, the boy had disappeared and has never been found. Here's a thread on his case.
