 The lead investigator in a high-profile Massachusetts murder case might lose his job. State Trooper Michael Proctor, who had to read his own text messages about the case to jurors, was relieved of duty shortly after a mistrial was declared. Prosecutors said they will pursue a second trial against Karen Reid. She's accused of hitting her boyfriend, Boston Police Officer John O'Keefe, with her car, killing him after dropping him off at a late-night house party.
