Authorities say a marital dispute apparently led a man to kill his wife, his 7-year-old son and the family dog in their Ocean County home before killing himself.

A spokesperson for the prosecutor’s office says that investigators are awaiting the results of an autopsy to determine how 51-year-old Gregg Scott died. But the wounds appear self-inflicted.

Officials say his wife, 48-year-old Kimberly Dunphey and his son, Owen Scott, died of blunt force trauma injuries.

The family and their dog were found dead Wednesday afternoon in their Lacey Township home.

Neighbors told News 12 New Jersey that they were shocked by what happened and that there didn’t appear to be a history of police activity at the home prior to the murders.
