Thermal imaging role at end of Boston manhunt

The manhunt for the remaining Boston Marathon bomber ended when he was discovered hiding in a boat in a back yard. As this page from NBC's Photo Blog shows, the fugitive's body can clearly be seen even though he was underneath a kind of tarpaulin that was protecting the boat from the weather. There's (over compressed) movie (pity about the commercial) but, further down, a couple of hi-res stills.

A further story explains more about the thermal imaging and, eventually, explodes the myth that you can see outlines of people through walls using far infrared/thermal imaging ... despite what CSI would have us believe. You can however see through thin sheets of plastic, such as a bin liner, at these wavelengths which can not be imaged with a conventional camera.
