Summary based on the NamUs case record (MP18471) and 2 other sources
In the summer of 1986, Arie Johannes de Slegge, a 63-year-old man, vanished from Las Vegas, Nevada. He was last seen in Clark County on July 15, 1986. Following that day, he was never heard from again, leaving behind a case with very few details for investigators to follow. At the time of his disappearance, de Slegge was described as a white male with gray, balding or receding hair, and brown eyes. He stood at approximately 5'7' and weighed around 150 pounds. The circumstances surrounding his disappearance remain largely unknown to the public.

The investigation into Arie de Slegge's disappearance is being handled by the Las Vegas Metropolitan Police Department. Despite the passage of many years, his case remains open, categorized as a missing person case. Information regarding what he was wearing at the time he was last seen or any personal belongings he may have had with him has not been made publicly available. Similarly, there is no public information about his means of transportation or any potential destination he might have been heading towards.

The lack of detailed information has made the investigation into Arie de Slegge's disappearance particularly challenging. His case is one of many cold cases involving missing persons that the Las Vegas Metropolitan Police Department continues to seek information on from the public. The official record of his disappearance was created on December 17, 2012, many years after he was last seen. The overview of this case is one of profound mystery, with no substantial leads or public updates provided over the decades, leaving his family and community without answers.
