Prosecutors say a man and his ex-wife were found dead in a Carlstadt home Saturday night hours after the man barricaded the home.
The incident developed early Saturday afternoon, when police went to see James Cox about the disappearance of his ex, Massiel Deoleo, with whom he had a young child. Police sources said the woman had a restraining order against him.
Cox, a convicted sex offender with family in law enforcement, barricaded himself in the home where he lived with his parents -- at one point requesting McDonald's from negotiators.
Crisis negotiators from the SWAT team were dispatched to the home and spent hours attempting to end the standoff peacefully after the first Carlstadt officer made contact with Cox around 12 p.m.
Police ultimately entered the house around 8 p.m. and found both Cox and the body of his ex-wife.
The Bergen County Prosecutor's Office said Cox is believed to have died by suicide after fatally shooting Deoleo sometime the previous night.
The investigation into their deaths is ongoing but investigators believe Cox was responsible for the woman's death.
