But her feelings about Zimmerman's actions are clear.
"George Zimmerman got away with murder, but you can't get away from God. And at the end of the day, he's going to have a lot of questions and answers he has to deal with," Maddy said. "[But] the law couldn't prove it."
Zimmerman concedes he shot and killed Martin in Sanford Feb. 26, 2012, but maintains he fired in self-defense.
"That's where I felt confused, where if a person kills someone, then you get charged for it," Maddy said. "But as the law was read to me, if you have no proof that he killed him intentionally, you can't say he's guilty."
Maddy, who only recently moved to Florida from Chicago, said she has had trouble adjusting to life after the verdict, and has wrestled with whether she made the right decision.
"I felt like I let a lot of people down, and I'm thinking to myself, 'Did I go the right way? Did I go the wrong way?'" she said.
