On January 27, 2011, 16-year-old Calyx Powers Schenecker was found dead in her home in Tampa, Florida. Calyx and her 13-year-old brother Beau were shot with a .38 revolver; Calyx was discovered in her bedroom and Beau in an SUV in the garage, their bodies covered with blankets. Their mother, 50-year-old Julie Powers Schenecker, confessed to killing both children, telling investigators she did so because they were mouthy. She was arrested and charged with two counts of first-degree murder.

Julie Schenecker’s defense team initially pursued an insanity plea. On May 15, 2014, she was found guilty of both counts of first-degree murder and sentenced to two concurrent life terms without the possibility of parole. The family had been the subject of earlier child abuse allegations made by Calyx; Julie acknowledged hitting her daughter in a prior incident but no charges arose. The children’s father, Parker Schenecker, later filed for divorce and pursued a civil wrongful-death lawsuit.

Does anyone have additional details about Calyx’s life or the family that could help build a clearer picture of what led to this tragedy?
