On November 20, 2018, 50-year-old technology executive Keith Caneiro was found shot to death on the lawn of his Colts Neck, New Jersey, mansion. Firefighters arriving at the property also discovered that Keith’s wife, Jennifer, 45, and their children, 11-year-old Jesse and 8-year-old Sophia, were dead inside the home. Authorities reported Jennifer and the children had been stabbed and their bodies badly burned in the fire.

Investigators focused on a family connection. Keith’s older brother and business partner, Paul Caneiro, was identified as a suspect. Prosecutors say the killings were motivated by money: the brothers ran a technology firm and a pest control company, and Keith had allegedly confronted Paul about missing funds and told him he would no longer be paid. Paul is also accused of setting a separate house fire in Ocean Township that same day; his wife and two daughters escaped that blaze unharmed.

Paul Caneiro was arrested and charged with four counts of murder plus aggravated arson and weapons offenses and has pleaded not guilty.
