It's a cornerstone of the American legal system and a virtual literary trope that people are presumed innocent until being proven guilty, but it sure was easy to assume the worst about fertilizer salesman Scott Peterson after his wife, Laci, and their unborn son, Conner, mysteriously disappeared in late 2002.

After all, here was a man who told his mistress that his then-pregnant wife was already deceased; provided conflicting information about what he was doing the day she was reported missing; was spotting laughing at Laci's candlelight vigil; and sold off her car in the weeks before her lifeless body was discovered. It was hardly the behavior of a devoted family man, and the public's suspicions were confirmed when a jury found Peterson guilty of double homicide in November 2004.

But the court of public opinion only goes so far amid the extensive layers of the legal system, and Peterson's appeals eventually earned a closer look as he waited out the years on death row, setting up the once-unthinkable possibility he would get another shot at freedom.

December 24, 2002: Laci is reported missing

Scott tells police that he had last seen Laci, nearly eight months pregnant with their baby, at their Modesto, California, home around 9:30 that morning before leaving to go fishing, sparking a massive manhunt comprised of both regional and federal authorities and volunteer search teams. Scott quickly draws the scrutiny of investigators, who note his seeming lack of concern over his wife's disappearance and his refusal to take a polygraph test.

Later that day, it is confirmed that the recently found bodies are those of Laci and Conner.

June 1, 2004: Scott's trial begins

The trial commences with the prosecution's opening statement, which asserts that Scott sought a responsibility-free life by killing his wife and soon-to-be-born son and dumping her weighted body in the bay. The following day, Geragos contends that his client's "boorish" behavior is hardly proof of murder, and offers a preview of the medical evidence that points to the baby being born after Laci's reported disappearance.

June 23, 2004: A juror is removed

August 10, 2004: Frey delivers her crucial testimony

Taking the stand for the first of her seven days of testimony, Frey, represented by celebrity lawyer Gloria Allred, recalls the details of her fairytale first date with Scott. She goes on to relate his claims of being a widower and numerous other lies, her accounts bolstered by the 12 hours of recorded phone calls played for the jury. Legal analysts later pinpoint this testimony as a huge momentum-shifter for the prosecution, to that point sputtering through a lack of firm evidence and its mishandling of procedural matters.

Following through on his opening promise, Geragos calls on a medical expert who testifies that Conner died no earlier than December 29, 2002, indicating that Laci was still alive after being reported missing. But the appearance ends badly for the witness, who concedes that he relied on hearsay to pinpoint the date of a pregnancy test, and at one point asks the cross-examining prosecutor to "cut me some slack."

After five months and more than 180 witnesses called to the stand, the jury is left to determine the fate of Scott.

The following day, foreman Gregory Jackson is also removed, reportedly at his own request after repeated clashes with his fellow jurors.

July 5, 2012: Scott files an appeal

In a 423-page document submitted to the California Supreme Court, Scott's lawyer revives the complaint that intensive publicity had eroded the possibility of his client receiving a fair trial. He also claims that Judge Delucchi had erred by excluding prospective jurors who opposed the death penalty but said they would consider imposing such a sentence, and that certain evidence, such as the findings of a police dog with a poor track record of success, should never have been admitted as evidence.

November 24, 2015: Scott files a second appeal

The habeas corpus petition covers much of the same ground as Scott's previous appeal, with one glaring difference: It includes the revelation that Nice, one of the late-trial replacements, had lied about an earlier involvement in legal proceedings by failing to disclose that she had once been threatened by her boyfriend's ex-girlfriend while pregnant.

August 24, 2020: Scott's death sentence is overturned
