Once Michael Marin heard the jury's verdict, he dropped his head into his hands in despair.
Video from inside the courtroom shows Marin slipping something into his mouth. Moments later, he did it again. After three minutes, he appeared to be in distress, coughing and gasping for air. He was rushed to the hospital and was later declared dead.
Authorities are conducting toxicology tests to see if he killed himself by ingesting poison. They are also questioning his attorneys, family members or friends to see if they know anything about the incident.
Marin was facing nearly 16 years in prison if he was convicted.
