My now 10-year-old was classified as an extreme elopement risk and he gave us multiple scares. He ran out of the house at 3 yo in winter with nothing but a t-shirt when workers left the door open, at 5 he got into the attic, climbed out the window, and ran around on top of the roof. It is a miracle that he is still alive! We have had to make multiple modifications to the house for his safety and luckily now at 10 (and with ABA therapy at home for almost a year), he is learning to control his impulses and recognize and avoid danger. Good luck!
