Witnesses in the Trayvon Martin case have changed their stories "in ways that may damage" George Zimmerman, according to new reports.
The four witnesses, all neighbors, were interviewed multiple times by police and special prosecutors about what they saw on February 26.
That was the night in which Zimmerman fatally shot Martin in Sanford, Fla.
Four days after the shooting, one woman told police she "saw two guys running" and then "a fistfight ... just fists, I don't know who was hitting who."
But on March 20, she told investigators she saw just one person.
"I couldn't tell you if it was a man, a woman, a kid, black or white," the woman, "Witness 2," said. "I couldn't tell you because it was dark and because I didn't have my contacts on or glasses. I just know that I saw a person out there."
Another witness, who was initially interviewed on March 20, said she saw two people on the ground immediately after the shooting.
She was not sure who was on top then, the Orlando Sentinel says. Six days later, however, she was sure: It was Zimmerman on top.
The woman, "Witness 12," said:
"I know after seeing the TV of what's happening, comparing their sizes, I think Zimmerman was definitely on top because of his size."
