It will be useful not only for investigators, but also for scientists. In addition to imagery, many sources also provide satellite data sets.
1. USGS Earth Explorer (https://earthexplorer.usgs.gov/). The official portal of the US Geological Survey, works all over the world. If difficulties arise, there is an official guide (https://gisgeography.com/usgs-earth-explorer-download-free-landsat-imagery/).
2. EarthData (https://search.earthdata.nasa.gov/search) by NASA. The wide range of satellites is striking. Works, again, all over the world.
3. DigitalGlobe Open Data Program (https://www.maxar.com/). This is the best place to go for high-precision satellite imagery.
4. JAXA's Global ALOS 3D World (https://www.eorc.jaxa.jp/ALOS/en/aw3d30/). The terrain is shown here accurately.
5. NOAA Digital Coast (https://coast.noaa.gov/digitalcoast/). As the name implies, information about the coasts is collected here.
