The jury deliberated for less than two days in the case, putting an end to the emotional trial.
The trial began Monday, March 25 with Jonathan Sander refusing to stay quiet. He shouted from the defendant's table that he was innocent, and instead pinned the killings on Sal Mazzella.
As Sal left the courtroom after the verdict had been read, Sander yelled: "Have a good day, Sal."
The judge warned Sander against outbursts like that because they can be used against him in the sentencing phase of his trial--which will begin Tuesday morning.
"Put me to death; that's what is happening anyway. I was framed. That's the way it is," Sander replied to the judge.
As for the trial, the evidence that may have been the most compelling against Sander was his taped confession. In it, he explained to investigators why and how he killed Sandy, Stephenie and Elaine Mazzella with a shotgun in March 2016.
Sander's defense team spent its time trying to convince the jury that the killings were not premeditated.
The jurors will return to court Tuesday morning to begin hearing evidence in the sentencing phase of the trial. Sander is eligible to receive the death penalty.
