Via Orlando Sentinel:
Evidence released last week in the second-degree-murder case against George Zimmerman shows four key witnesses made major changes in what they say they saw and heard the night he fatally shot 17-year-old Trayvon Martin in Sanford.
Three changed their stories in ways that may damage Zimmerman. A fourth abandoned her initial story, that she saw one person chasing another. Now, she says, she saw a single figure running.
They were reinterviewed in mid-March, after Sanford police handed the case off to State Attorney Norm Wolfinger. The case changed hands again when Gov. Rick Scott passed it on to a special prosecutor. Zimmerman was arrested April 11 on a charge of second-degree murder.
