Sander stayed stoic when prosecutors revealed gruesome crime scene photos of his three murdered neighbors. He didn't flinch when the jury unanimously convicted him of those murders.
What did bring him to tears? Letters from his children.
Earlier in the trial, Sander had several outbursts and has been physically restrained during most of the proceedings after an incident on the first day of trial. But when letters from his children were read aloud, the stoic anger melted away.
'Hey dad. I really, really love you. I also missing you. I miss you every day,' said one.
A deputy eventually came over and handed tissues to a shackled Sander.
On Monday, when he was convicted of murdering the three Mazzella family members, he just stared straight ahead.
As one victim's distraught relatives were leaving the courtroom, Sander began taunting that family member.
Sander yelled, "See you soon Sal, have a nice day."
The incident happened when the jury was out of the room.
The prosecution played a video of the interaction and said it shows Sander is a calculating individual.
"My position is he knows what he's doing when he's doing it," said Prosecutor Melanie Shekita. "This is not a man who can't control his emotions and actions. He chooses when to do so."
Closing arguments will begin Friday. The jury is expected to get the case thereafter and start deliberating.
If Sander gets the death penalty, he will be the second person to receive the sentence in Wake County within the last decade. On March 4, Seaga Gillard was convicted of first-degree murder in the deaths of April Lynn Holland, who was pregnant, and Dwayne Garvey.
