"Subsequent investigation and interviews raised substantial doubt about the felony charge, specifically including whether the young lady was incapacitated during the encounter."
It said that, while charges were pending in May 2012, Barnett's lawyer tried to take sworn statements from the alleged victims and their relatives, but they "refused to answer any questions citing their Fifth Amendment right to not incriminate themselves. Accordingly, without competent evidence and with witnesses unwilling to testify, the State was under a duty to dismiss any prosecution when it became apparent that a conviction was not possible."
That left Barnett facing one remaining claim, a misdemeanor charge of child endangerment related to the allegation that the high school senior left the 14-year-old girl "in an incapacitated condition outside of her home in freezing weather."
During a deposition in July 2012, Daisy testified "with numerous inconsistencies and changes to previous statements," the statement from Barnett's lawyer says. "When the alleged victim's mother was questioned about these changes, she freely admitted that her daughter does not always tell the truth, particularly when she is in a stressful situation. Thereafter, the misdemeanor charge was dismissed."
That account was corroborated by Nodaway County Prosecuting Attorney Robert L. Rice. "There was insufficient evidence to prove a criminal charge beyond a reasonable doubt," he said in a statement. "The State's witnesses refused to cooperate and invoked their Fifth Amendment privilege to not testify."
Nodaway County Sheriff Darren White told CNN that his office and the prosecuting attorney had been ready to prosecute but did not move forward because the victim and her family refused to cooperate.
"The only people's stories that have been inconsistent throughout this whole thing are the Colemans' -- are the victims' in this case -- and I don't know why that is," White said.
Reacting to the lieutenant governor's call for a grand jury review, the sheriff said that his office handled the case "flawlessly."
"My initial reaction would be that apparently the lieutenant governor has chosen to simply also get involved in the hype and the social media because at no point in time has the lieutenant governor's office made any request to see any actual reports," he said Tuesday night on CNN's "Erin Burnett OutFront."
"That being said, I would welcome someone from the outside coming in and taking a look at this case because there's no doubt in my mind that everyone would be vindicated from all of these absolutely outrageous accusations," White added.
The story has been picking up steam on social media since the Star's weekend report.
A Facebook page called "Justice for Daisy" is calling for a protest at the Nodaway County courthouse next week.
Anonymous also appears to be involved. The loosely organized hacker group released a statement calling for an investigation into the handling of the case.
It made similar calls around a separate teenage rape case in Steubenville, Ohio, recently.
Two teenage boys were convicted in that case, which gained worldwide attention because of -- and through -- the use of social media.
Melinda Coleman denied that she had not cooperated with investigators. "I told them everything," she told CNN on Tuesday. "That's absolutely not true, and it still kind of shocks me that they're lying about it."
She said she was simply seeking justice and peace for her family. "I don't want to be threatened and fearful any more," she said.
Retaliation from town?
Daisy said that she was targeted by cyberbullying after she leveled the accusations and that took a toll on her. "I really did start to hate myself."
She said the fact that Barnett comes from a prominent political family -- his grandfather Rex Barnett is a former state representative -- might explain why the charges were dropped. "Yes, I do believe that it did play a role," she said.
