Investigating the Freddie Gray case

Baltimore Detective Timothy Hamilton moves sophisticated image-gathering equipment into position to scan the area on Bruce Street, across from Gilmor Homes near Presbury Street, to create a 360-degree, high-resolution visual of the area.

Crime lab recording technician Thomas Wisner uses a $236,000 Leica ScanStation C10 laser imaging system to create 3D images of the Gilmor Homes in Baltimore. The scans were made of the streets, sidewalks and terrain of Freddie Gray’s chase by police and the route of the van that took him to the Western District police station.
