A high-angle forensic view captures a solitary individual engaged in construction work on a gravel-covered rooftop in Nijmegen, Netherlands, under clear daylight conditions

A high-angle forensic view captures a solitary individual engaged in construction work on a gravel-covered rooftop in Nijmegen, Netherlands, under clear daylight conditions. **Environment:** The rooftop is predominantly covered with diverse-sized, dark grey and light grey river pebbles, serving as ballast for the roof membrane. The ground shows distinct shadows, indicating strong sunlight. Several reddish-brown, rectangular rubber pads or pavers are scattered on the gravel in the foreground, likely for supporting equipment or distributing weight. **People:** One individual, wearing a grey hooded jacket, dark work trousers with side pockets, a dark beanie, and tan work boots, is centrally positioned, bent forward and to the right. The person wears dark work gloves, actively holding and adjusting a long, bright yellow bar, which is integrated with a linear arrangement of grey metal framework. **Objects and Actions:** The grey metal framework, consisting of multiple interconnected angular sections, extends diagonally across the scene from the lower left to the upper right. These structures, along with the yellow bars (which appear to be leveling or spacing guides with small white clips), are consistent with components for solar panel mounting systems. The individual's action suggests assembly or precise positioning of these components. **Background:** In the background, various rooftop mechanical installations are visible. To the left, a corrugated metal structure, possibly an equipment enclosure, features a vertical grey pipe and a white metal ladder. To the right and extending horizontally, several large, white, rectangular HVAC ducts or air handling units are elevated on short supports above the gravel. Further in the distance, a line of trees and indistinct building structures are visible under a bright sky.
