Juror B29 was the only minority on the all-female jury that acquitted Zimmerman for the shooting of Martin. Identified only by her first name, the mother of eight talked exclusively with ABC's Robin Roberts.
Maddy, who is Puerto Rican, expressed conviction and regret, saying she feels she owes Martin's parents an apology because she feels "like she let them down." Zimmerman, who admitted shooting the unarmed 17-year-old, was found not guilty of second-degree murder and manslaughter.
"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.
The 36-year-old juror said "you can't put the man in jail even though in our hearts we felt he was guilty."
Maddy said she favored convicting Zimmerman of second-degree murder and fought for it, saying she was "the juror that was going to give them the hung jury."
Juror B37, who was the first to speak publicly last week, said when they took their first vote after receiving the case, the majority of the women believed Zimmerman was not guilty.
"There was a couple of them in there that wanted to find him guilty of something. And after hours and hours and hours of deliberating over the law, and reading it over and over and over again, we decided there's just no other place to go," said Juror B37.
Their verdict sparked angry protests in cities across the country. Maddy says by the second day of deliberations, she realized there wasn't enough evidence to convict Zimmerman of a crime under Florida law.
"The law couldn't prove it, but you know, the world goes in circles, so we just have to believe in the lord that if he has to pay, he will pay," said Maddy.
Maddy also said she doesn't think the case should have gone to trial, calling it "a publicity stunt." She says she has had trouble adjusting to life after the verdict and says she still wrestles with her decision.
