Dr. Fernando Morales is a Deputy Medical Examiner for the Los Angeles County Department of the Coroner. He consults with the MCD on cases of suspicious or unknown death, and is responsible for determining whether an individual died by natural causes, or whether the death was accidental, a suicide or a homicide. He is also responsible for determining cause of death. According to his interview on Identity, he is an immigrant.
In "White Lies, Part 1", he is present in the courtroom when Dwight Darnell opens fire. After Assistant Chief Russell Taylor is shot, Morales rushes to his side in an attempt to save his life. Morales ultimately fails and Taylor dies despite his efforts. As much effected by the tragedy as the squad, he aids them in protecting Doctor Joe Bowman by officially declaring him dead to prevent further attempts on the man's life.
