After four full days of deliberations, jurors told the judge no matter how much information they received, it wouldn't help.
Judge John Lua declared a mistrial.
Family members of both Oliver and Bowe Cleveland were in court as they judge declared a mistrial Tuesday afternoon.
Oliver's mom hugged supporters and cried, while Cleveland's family remained emotionless to the news.
A gag order is still in place, so we can't speak with family, witnesses, attorneys-- anyone still tied to the case.
But we could speak to jurors, once they were released. 61-year-old Al Miller said he doesn't believe Oliver is a killer.
Al Miller said, "you don't take matters into your own hands, but I'll tell you who I think the perpetrator of this is.. the whole ordeal... is the Taft school. They didn't step up and do a lot more. This boy was crying out for help, and I don't think they really gave it to him."
Juror number two, the foreman, would not tell us his name but he said the jury voted six times. During those votes, jurors said they were no where near a unanimous decision.
There was no question Oliver shot classmate Bowe Cleveland in the chest with a 12 gauge shotgun. Oliver admitted he pulled the trigger, jurors had to decide why.
Oliver testified that he was gay and he was relentlessly bullied about his sexual orientation.
He said he blacked out before and during the shooting on that Thursday, January 10, 2013.
On that day authorities say, then, 16 year old Bryan Oliver, came to school with a 12 gauge shotgun and a pocket full of more than two dozen shells, and took to the stairs to first period science class.
Teacher Ryan Heber and campus supervisor Kim Fields talked Oliver into putting the gun down to surrender.
And almost two years later some residents of Taft say they don't see Oliver as a criminal. Instead, like one of the jurors, they question why he didn't receive help from the school district.
One resident still uses this case as an example for her own children. Starla Lopez has two sons that attend Taft Union High School.
She said, "I tell them 'you know, if somebody's picking on you, you're going to have to stand up for yourself now. You can't depend on somebody else, the school district or the teachers. The only way they'll get out of it is if they just confront the person that's harassing them."
Another trial is scheduled to begin January 26.
