Dead Scientists can be obtained from one of two ways: enter the Newton system in the Kepler Verge, or from reading a security terminal on Noveria.
The mission takes place on Ontarom. The mission can ultimately be resolved via a Paragon or Renegade choice; if you choose Paragon, you'll convince Toombs to disarm and arrest the scientist. If you choose Renegade, you'll shoot Toombs, and the scientist will give you a sum of credits; you can still arrest the scientist.
