Paul Caniero is accused of killing his brother and his brother's entire family inside their home in Colts Neck, New Jersey in 2018, before setting the home on fire.
The violence stemmed from a business dispute.
Inside the courtroom on Tuesday, the battle over what evidence should or would not be presented before the jury took up the entire morning, long after jurors were scheduled to be seated.
It led to some fiery exchanges between the attorneys in the case and Monmouth County Superior Court Judge Marc Lemieux.
The jury was finally seated at about 1:45 p.m., and testimony continued once again with Katelyn Caneiro, and a piece of evidence, video from police body cameras showing her and her father outside their burning home on November 20, 2018, being questioned about security camera recordings in their home, and later, on finding out that her relatives' mansion had also been set on fire and that they were shot and stabbed to death.
The last witness in the case was Katelyn Caneiro's sister Marissa. Her testimony took less than five minutes total.
She was asked about her father's reaction at the police station on finding out about the quadruple murder of his brother Keith and his family.
"My dad was really upset and crying," she said. "He fell to the floor. I was sitting across from him at that point."
Paul Caneiro stood to once again reiterate his decision not to testify.
Both sides rested their cases.
The jury is back on Wednesday for summations from the attorneys, and instructions from the judge, and could begin deliberating soon after.
