Authorities have confirmed that a man fatally shot his partner and their two children before setting their Jersey shore house on fire and killing himself.

Monmouth County Acting Prosecutor Christopher Gramiccioni on Friday officially ruled the deaths of 35-year-old Lyndon Beharry, 29-year-old Amanda Morris, 7-year-old Brandon Beharry and 4-year-old Brian Beharry a murder-suicide.

He says all four were found with gunshot wounds inside a second-floor bedroom after Tuesday's fire was extinguished. He says Lyndon Beharry's gunshot wound was self-inflicted.

The outside of the home showed little fire damage, and all of it was confined to the second floor.

A cousin says he saw Lyndon Beharry earlier Tuesday and everything seemed fine with the family.
