Earlier this week, the California Supreme Court shocked the nation by overturning the death sentence of Scott Peterson, who has spent the past 15 years on death row after being convicted of the 2002 murders of his wife Laci and their unborn son Connor. Days later, a source has come forward to reveal how Laci’s family is handling the court’s ruling.

“The family is in pain again,” says a source close to Laci’s family told PEOPLE magazine. “It’s not even so much that’s he’s getting off death row for the time being, but now there will be another trial and they’re going to have to sit through it and possibly testify.”

Peterson, now 47, was found guilty on two counts of first-degree murder for Laci and Connor’s deaths, and he was sentenced to death in 2005. On Monday, California’s Supreme Court reversed the death penalty, but left his conviction in place.

“Peterson contends his trial was flawed for multiple reasons, beginning with the unusual amount of pretrial publicity that surrounded the case,” the court said in the ruling. “We reject Peterson’s claim that he received an unfair trial as to guilt and thus affirm his convictions for murder.”

However, the court added that the trial judge “made a series of clear and significant errors in jury selection that, under long-standing United States Supreme Court precedent, undermined Peterson’s right to an impartial jury at the penalty phase.”

Prosecutors will now have the option to try Peterson again for the death penalty in the case, which became a national sensation in the early 2000s.

Peterson allegedly murdered Laci when she was eight months pregnant with Connor on Christmas Eve in 2002. He then dumped their bodies into the San Francisco Bay from his fishing boat, and it took months for them to be found. During the time Laci was missing, a media circus formed around the case as it captivated the entire country.

Now that Peterson’s future is uncertain, Laci’s family is still processing this new development while also trying to prepare themselves for tough times ahead.

“The old wounds are being reopened yet again,” the family source said. “There is no end to the pain that Scott Peterson has put this family through.”
