Shellie Zimmerman said Thursday that a recent spat with her estranged husband, George Zimmerman, has left her with doubts about him and conflicted over what happened the night he shot and killed 17-year-old Trayvon Martin.
She spoke with NBC's TodayShow in her first interview since the couple's row at a family home in Florida Sept. 9.
She had told police in a 911 call that her husband had threatened her with a gun and had punched her father in the nose. The police said later that they did not find a gun, and she told Today's Matt Lauer she never actually saw a gun.
"This person that I'm married to, that I'm divorcing, I've kind of realized now that I don't know him," the 26-year-old Zimmerman told Lauer. "And I really don't know what he's capable of."
Although she declined to file charges over the clash, she said it has made her reconsider what happened the night her husband, a neighborhood watch volunteer, fatally shot the unarmed teen.
"I'm conflicted on that," she said. "I believe the evidence, but this revelation in my life has really helped me to take the blinders off and start to see things differently."
Lauer pressed further, asking, "So you now doubt his innocence, at least the fact that he was acting in self-defense on the night that Trayvon Martin was killed?"
"I think anyone would doubt that innocence because I don't know the person that I've been married to," Zimmerman. "I have doubts, but I also believe the evidence."
She also strongly denied that George Zimmerman had racially profiled the black teenager.
George Zimmerman, 29, was acquitted by a Florida jury in July of charges of second-degree murder and manslaughter for the 2012 killing of the teen, who was walking through the gated community to his father's house. He had argued that he shot Trayvon in self-defense.
Shellie Zimmerman stopped short, however, of claiming that the African-American teenager was racially profiled.
She also told Today that her marriage began to fall apart after the trial.
"(George) just kind of treated me like I was disposable," she said. "After standing by him, he kind of left. And I guess he kind of went on a victory tour without me.
"And I thought I was living a life with him and that we were going to kind of rebuild after all of this - and he had other plans for me."
Today said representatives for George Zimmerman "were not interested in commenting" on the interview.
Shellie Zimmerman is on probation for a misdemeanor perjury charge after admitting to lying at her husband's bail hearing.
Her lawyer said divorce papers have been filed but not yet served because George Zimmerman's whereabouts are unknown.
