"They had to come back again and more or less relive what happened years ago," said prosecutor Dwight Nadamoto.
But Stangel's victims and their families spent the past week fighting their emotions, day in and day, out facing the man who went on a shooting spree nearly two years ago.
On Thursday, a jury convicted him of second degree murder in the death of Tammy Nuygen, who was shot and killed at a stop light in Kaimuki.
Stangel was also convicted on two charges of second degree attempted murder for shooting and hurting Amy Asuncion and Michael Pagaliau that night.
"It is a heart-wrenching case if you think about it. The victims who are just going about their way working, going home, and for no reason someone just starts shooting at them," said Nadamoto.
Stangel was also convicted on six firearms related charges, but felony charges were reduced.
Stangel's attorney said that showed an acknowledgement his client was not in his right frame of mind.
"We did not dispute facts of the case. My challenge to them was to look into Stangel's state of mind," said defense attorney John Schum.
After the verdict was read Stangel's family walked out together, quiet and collected.
His father knows his son will pay for his crimes for a long time.
"This is their son. They love their son. Is their son a saint? No. Did Toby do something wrong? Yes. We did not fight what we thought was wrong, but did not fight what wasn't," said Schum.
"Hopefully it sends a message that you don't go around shooting people," said Nadamoto.
Three drug charges were thrown out, because the jury could not reach a verdict.
There will be a re-trial on those charges.
The prosecution requested an extended sentence hearing that Circuit Court Judge Glenn Kim scheduled to begin Monday morning.
Due to several reduced felony charges, Stangel is still eligible for parole.
