JACKSONVILLE, Fla. -- She's faced with the reality her father may spend the rest of his life in prison. For the first time since Michael Dunn's conviction his daughter is breaking her silence. First Coast News Anchor Heather Crawford has been in contact with Rebecca Dunn for months, and in partnership with ABC News she is sharing her emotional story.

"He had to do something completely horrible to save his life, and now he's in jail for it, for protecting himself," said Rebecca Dunn wiping away tears.

Rebecca is still in shock her father, 47-year-old Michael Dunn was convicted Saturday of three counts of attempted second-degree murder.

"It's just not right, not right. My world has completely changed," said Rebecca.

The minimum sentence for those three counts will likely keep her dad in jail until he is more than 100 years old.

"The fact that he is facing 60 years is crazy to me. I will do anything I can to help get him out. I don't know how, but I know there's another way. We will find another way to get him out. He is not going to be there forever," said Dunn's daughter.

EXCLUSIVE: Dunn's daughter, 'It should never have happened.'

Rebecca spent a few days in Jacksonville during her father's trial before going back to her home in Iowa. She said she learned he had been convicted through Facebook.

"I can't imagine living life without him, and I have this whole year. I want him to know I love him so much, and I'm always here. I will never stop fighting for him. I believe him and I know the truth," said Rebecca.

While her heart is heavy she also feels for the family of Jordan Davis, who her father was charged with murdering.

"I always wanted to tell them how sorry I was. Honestly, when I see them I want to run up to them and give them a hug, but I don't think that would be a good idea. I pray for them that they get through this. I know they are suffering just like my family is, but they will never ever see him again. I can at least see my dad in jail," said Rebecca.

Michael Dunn is scheduled to be sentenced in late March. State Attorney Angela Corey says she plans to retry him on the one charge jurors could not reach a verdict on, first-degree murder, after the judge declared a mistrial on that count.
