That juror said the actions of Zimmerman and Martin both led to the teenager's fatal shooting, but that Zimmerman didn't actually break the law.
Juror B29 also told ABC that she didn't believe race was an issue at the trial. Though the judge so far has refused to release the names or biographical information about the jurors, B29 said she was 36 years old and Puerto Rican.
Martin was black and Zimmerman identifies himself as Hispanic. Martin's parents believe Zimmerman racially profiled their son when he started following him after spotting him walking through the neighborhood where Zimmerman lived and Martin was visiting. B29 said she couldn't speak for her fellow jurors on the race issue. The other women on the jury were white.
Juror B29 is a nursing assistant and mother of eight children who recently moved to Florida from Chicago.
She said she feels like she owes Martin's parents an apology.
"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. "As much as we were trying to find this man guilty ... They give you a booklet that basically tells you the truth, and the truth is that there was nothing that we could do about it."
