Mark Edmonson was 42 when he was last seen at about 9:30 p.m. on October 3, 1999, at his sister’s home in Hamilton. He left that evening carrying two black plastic bags and two long hunting knives and is believed to have gone without money or identification. Mark is described as developmentally challenged, a detail that has long heightened concern for his safety.

Family members recall that he had talked about wanting to go on the road, a remark that may reflect his state of mind before he vanished. Despite extensive searches and an investigation by law enforcement, there has been no confirmed contact with Mark since that night and no definitive answers about where he went or what happened to him.

If anyone has memories of Mark from Hamilton or Stoney Creek around October 1999, or information about someone fitting his description seen after that date, please share what you know.
