The widow of the Pulse nightclub gunman has been found not guilty of charges that she tried to mislead investigators and aided her husband in the attack that killed 49 people.
Noor Salman, 31, could have faced up to life in prison had she been convicted of charges of obstruction of justice and aiding Omar Mateen in providing support to the so-called Islamic State militant group.
Instead the jury in US District Court acquitted Ms Salman after roughly 12 hours of deliberation since Wednesday.
Mateen died in an exchange of gunfire with police at the nightclub. At the time, Ms Salman was home with the couple's then 3-year-old son.
"We knew from day one she was innocent," her aunt Susan Adieh told reporters just after the verdict.
The acquittal is likely to be an emotional blow for the survivors and families of those killed at Pulse.
At the time of the massacre on 12 June 2016, it was the deadliest mass shooting in modern US history.
It has since been surpassed by the Las Vegas attack in which a shooter opened fire on an outdoor concert from his hotel room last year, killing 58.
Ms Salman broke down in tears after verdict and hugged her defense lawyers when US District Judge Paul Byron announced the not-guilty verdict, CNN reported.
Lead defense attorney Charles Swift bolted with joy and Ms Salman's relatives were heard crying, according to reporters inside the courtroom.
"I don't know how we're going to make up for the last two years," Ms Salman's uncle Al Salman told reporters.
"I told you, and I can tell you now, that she's innocent."
Mateen, 29, opened fire shortly after 2am during the club's popular Latin night.
He shot patrons on the dance floor and sprayed bullets at others cowering in bathroom stalls.
Holding hostages during his standoff with police, Mateen claimed allegiance to a leader of the self-styled Islamic State militant group.
He was killed in an exchange of gunfire with authorities.
Prosecutors said Ms Salman cased possible attack sites with her husband and did nothing to stop his plans.
They claimed she initially told investigators her husband acted without her knowledge but later said she knew he was watching Islamic State recruitment videos, had purchased an assault rifle, and examined three possible attack locations.
Defense attorneys said Ms Salman was a "simple woman who loved children" and did not know of her husband's intentions.
Defense attorney Linda Moreno told jurors the FBI did not record its interrogation and coerced Ms Salman into making statements that favoured the prosecution.
The defense said prosecutors could not show any direct links between Mateen and IS and provided no evidence that Ms Salman aided her husband.
