A family of four found dead at their mansion in Colts Neck, New Jersey, were the victims of homicide and their house was subsequently set on fire, Monmouth County Prosecutor Christopher Gramiccioni said Wednesday.
"Today our investigation has revealed that unfortunately, sadly, each of these individuals were the victims of homicidal violence at some point prior to when the fire was set," he said.

Keith and Jennifer Caneiro were identified as two of the victims, and Gramiccioni said they had tentatively identified the other two bodies as those of the Caneiro children, 11-year-old Jesse and 8-year-old Sophia.
Keith Caneiro had been shot and was found in front of the home and the other three were found severely burned inside the home on Tuesday. Authorities have no reason to believe there was "a suicide angle" in this case, Gramiccioni added.
Gramiccioni said authorities are investigating a separate house fire in nearby Ocean Township as arson and are looking into whether the two fires are related.
The other house is the residence of Paul Caneiro, the brother of Keith Caneiro, Gramiccioni said. Their two homes are about 11 miles apart.
Brother accused in another fire
Paul Caneiro, 51, was arrested Wednesday and charged with second-degree aggravated arson in connection to the fire Tuesday morning at his Ocean Township home. He faces 5-10 years in prison if convicted and will be in court November 28 to face that charge and a detention review.
"My client maintains his innocence on this charge and any other potential charges," Caneiro's attorney, Robert Honecker, told CNN. "His family fully support his defense of this charge. He fully expects to be vindicated when this case finally resolves."
Authorities say Paul Caneiro set fire to his house by igniting gasoline while his wife and two daughters were inside, according to the complaint and warrant provided by Monmouth County prosecutors. There were no injuries in that blaze.
Brother helped his family get out, lawyer says
Paul Caneiro "was devastated to find out that there was a fire at his brother's residence and they were reporting at the time that there was a fatality," Honecker told CNN on Saturday.
Caneiro helped his family evacuate and waited with his family until police and fire arrived, his attorney said. He then went voluntarily to the police headquarters in Ocean Township with his wife and two daughters where the family was questioned, Honecker added.
Gramiccioni cautioned against leaping to conclusions about the fires until authorities investigate further.
"Both of those homes that we are talking about, they're owned by -- under public records -- by common family members," Grdamiccioni said.
"I would just encourage the media and the public to not get carried away until there's reason to believe whether that might be linked or not. It's important not to do that until there is an objective reason to do so."
The call for the Colts Neck fire came in at 12:38 p.m. on Tuesday -- more than seven hours after the Ocean Township fire -- and more than 20 fire departments responded. Authorities said they were not aware of any law enforcement calls to the home before that time.
Brothers worked together
Paul and Keith Caneiro are the sole officers of a company that involved the sale and service of computers, according to New Jersey business records.
Records from 2014 show that Paul and Keith Caneiro registered an Asbury Park-based company named Jay-Martin Systems that was doing business as "Square One." The company is described as engaging in the "sales and service of computers." A 2007 filing indicates that Keith was the president of the company.
The brothers were best friends who talked almost daily, Honecker said Saturday, adding he had no reason to believe there was animosity between them.
The documents listed the home addresses for Keith Caneiro and Paul Caneiro, which were the sites of the fires in Colts Neck and Ocean Township, respectively.
