UPDATE, 1:20 p.m. ET: Trayvon Martin's mother Sybrina Fulton, who said on the "Today" show early Thursday that she believed the killing of her son was an "accident," has retracted those comments.
"George Zimmerman stalked my son and murdered him in cold blood," told MSNBC in a separate interview.
EARLIER: Trayvon Martin's mom, Sybrina Fulton, said in an interview on the "Today" show Thursday that she believes it was "an accident" that George Zimmerman shot and killed her son in Sanford, Fla., on Feb. 26.
"I believe it was an accident," Fulton said. "I believe that it just got out of control, and he couldn't turn the clock back. I would ask him, did he know that that was a minor, that that was a teenager and that he did not have a weapon? I would ask him that I understand that his family is hurting, but think about our family that lost our teenage son. I mean, it's just very difficult to live with day in and day out. I'm sure his parents can pick up the phone and call him, but we can't pick up the phone and call Trayvon anymore."
Zimmerman, who is being charged with second-degree murder, is currently being held in protective custody at the Seminole County jail, awaiting a court appearance.
Earlier in the interview, Fulton said she is prepared to endure the trial, "even if that means that he may be found not guilty."
"We just want him to be held accountable for what he's done," Fulton said. "And by him not being arrested, that would not have been done. So we are happy that he was arrested so that the committee gives his side of the story."
Tracy Martin, Trayvon's father, said he believes police bungled the investigation, which led to the delay in Zimmerman's arrest.
"First and foremost, I think had the Sanford Police Department done a thorough investigation from the beginning, George Zimmerman would have been locked up from day one, and there wouldn't have been such a huge public outcry for the arrest," Tracy Martin said. "And if, in fact, we had to plead our case to public officials just to get him arrested, if that's what we have to continue to do to plead our case, then that's what we'll do."
