Robert Dienes, 67, and his wife Myriam Dienes, 56, were found shot to death in their Tampa home on August 20, 2015. Investigators ruled both deaths homicides after both were discovered at the scene.

Police focused on the couple’s 21-year-old stepdaughter, Nicole Nachtman, who had driven from Tallahassee to Tampa. Prosecutors said she shot Robert inside the house, then waited and shot Myriam in the driveway as she returned. Neighbors reported hearing gunshots and seeing a shadowy figure fleeing the scene.

At trial the defense presented evidence that Nachtman suffered severe mental illness, including schizophrenia, and alleged she had been abused by her mother and was psychotic at the time. The prosecution argued Nachtman knew right from wrong and planned the killings. After a week of testimony and nearly 12 hours of deliberation, the jury found Nachtman guilty and she was sentenced to life in prison without parole.

Did anyone in the Tampa or Tallahassee area know the Dienes family or have information about tensions within the household?
