Authorities found the family of four mortally wounded after being called to the Long Branch, New Jersey home after receiving reports of a fire 

The couple and their two children were taken to a hospital, but they could not be saved and later died. The exact cause of the four family members' deaths are still under investigation but it appears all four suffered gunshot wounds. Lyndon Beharry worked for the city's public works department.'He was an excellent mechanic and a very good-natured person,' department director Fred Migliaccio told the Asbury Park Press.Investigators determined that the blaze ignited in more than one spot, and it didn't appear to be accidental, LeMieux said.A cousin of Lyndon Beharry was alarmed to hear about the murder-suicide since he had attended a barbecue with his cousin earlier that night and all seemed fine.

'We were like brothers. We would go to the water parks with the kids on the weekends. I don't know how they could say this. They lived very happily,' Ronald Beharry, who was also a neighbor, told the newspaper. However, a neighbor said that they heard the couple arguing on the porch the day before the fire, according to CBS New York. The outside of the home showed little fire damage and all of it was confined to the second floor.
