Blayne Alexander joins Keith Morrison to discuss her episode, “The Death of Dr. Schwartz.” In 2014, Dr. Steven Schwartz was found murdered in his Tarpon Springs, Florida, home. What initially looked like a burglary gone wrong turned out to be something much darker. Investigators uncovered a story of greed, betrayal, and a hidden past that stunned even those closest to the doctor. Blayne shares her experience reporting the case across Florida, Texas, New Mexico, and Albania — where she spoke to a man who was convicted in connection to the crime. She also shares her conversation with Detective Lara Scarpatti, one of the first officers on the scene, about the unusual behavior she noticed that night.
