James “Jimmy” Scandirito Jr. became the focus of a bizarre Florida homicide investigation after his father, former Macomb County District Judge James “Skip” Scandirito Sr., disappeared from his Boca Raton home in March 2018. Scandirito Jr. initially told investigators that his 74-year-old father had gone missing. Police soon identified inconsistencies in his account and began monitoring his movements. On April 3, 2018, investigators followed Scandirito Jr. to the former Ocean Breeze Golf Club in Boca Raton. Human remains were subsequently discovered at the abandoned golf course and identified as those of James Scandirito Sr. His body had been dismembered and parts had been concealed in bags and buried. Scandirito Jr. was arrested and charged with first-degree murder. Prosecutors argued that he killed his father for financial gain, pointing to evidence that he was his father's sole beneficiary and had attempted to access his father's financial accounts after his death. (wpbf.com) At trial, Scandirito Jr. admitted that he had dismembered and disposed of his father's body but denied killing him. He testified that he and his father had been drinking and using drugs on March 28, 2018, and that he discovered his father unresponsive after leaving the room. He claimed that he panicked because he feared being blamed for the drugs and decided to dispose of the body rather than contact police. (lawandcrime.com) The medical examiner could not determine the cause of James Scandirito Sr.'s death because of the condition of the remains. On March 21, 2019, a Palm Beach County jury found Scandirito Jr. not guilty of first-degree murder but guilty of abuse of a dead human body. He was sentenced to 15 years in prison. (wpbf.com)
