You've discovered the body of a scavenger who was killed by a highly infectious disease. SAM recommends finding the source to prevent the disease from spreading.
- Scan the scavengers' bodies
Scavenger bodies in question are generated at random but can be found at scavenger outposts dotted all over the map.
Once you've scaned enough bodies, SAM will prompt you that the death was caused by ingestion of contaminated meat, and provide the navpoint to the alledged source.
On site, scan the area and you'd find a cluster of containment canisters that are tainting the local wildlife. Follow action as prompted and the mission is completed.
