Psychologist on evaluating Noriella Santos
Dr. Dawn Hughes is a forensic psychologist hired by Noriella Santos’ defense team to evaluate her mindset before, during and after the 2009 murder of Michael Sinclair. Dr. Hughes tells CBS News' Jim Axelrod about the psychological trauma inflicted on Santos by her then-boyfriend, Daniel Greenspan, who was convicted for the murder in March 2017—and why that trauma might explain Santos’ involvement in this case.
