John Giandoni was 40 when he was found dead in his Ballston area townhouse in Arlington, Virginia, on March 16, 2018. Police responding to a welfare check discovered he had sustained gunshot and stab wounds and that a zip tie had been placed around his mouth. His death was ruled a homicide.

Investigators uncovered a strained custody situation involving Giandoni, his former girlfriend, and their son. The ex-girlfriend was reportedly in a relationship with 42-year-old Jitesh Patel of Woodbine, Maryland. In July 2018 Patel was arrested and charged with murder, armed burglary, and related firearm counts; prosecutors said he broke into Giandoni’s home and shot, stabbed, and choked him, possibly to help his girlfriend in the custody dispute.

Key evidence described by prosecutors included surveillance footage showing a minivan like Patel’s arriving and someone entering the townhouse the afternoon of the killing, a person leaving hours later and driving away in the van, and a 9mm pistol and matching ammunition recovered at Patel’s residence. Patel was awaiting trial when he was found dead in his Arlington County jail cell on November 11, 2019; the medical examiner was to determine the cause of death.
