Friday, May 25, 11:08 a.m. EDT: Zimmerman made self-incriminating statements: Neighborhood-watch captain George Zimmerman made statements to police that help establish his guilt in the second-degree-murder case against him for killing unarmed black teenager Trayvon Martin, prosecutors said in a court filing on Thursday, the Chicago Tribune reports.

Thursday, May 24, 9:49 a.m. EDT: Tapes reveal that Zimmerman called police "lazy" and "disgusting": A year before George Zimmerman shot and killed 17-year-old Trayvon Martin, he told a City Hall community forum and then mayor-elect that Sanford police were "lazy."  He came to this conclusion from ride-alongs with the department, reports the Miami Herald.

Wednesday, May 23, 9:09 a.m. EDT: Reinterviewed witnesses now have accounts unfavorable to Zimmerman's defense, the Orlando Sentinel reports. Three of the four witnesses who saw the confrontation between slain Florida teen Trayvon Martin and George Zimmerman have now changed their accounts of what they observed. One woman, identified only as Witness 12, initially told police that she saw two people on the ground the night of the shooting but was unsure who was on top. According to the Sentinel, "Six days later, after seeing news reports, she said she believed Zimmerman was on top of Martin."

Monday, May 21, 10:03 a.m. EDT: 911 call leads experts to reach two very different conclusions: Legal experts say that the 45-second recording of the call to 911 made between 7:16:11 p.m and 7:16:56 p.m. on the night George Zimmerman shot and killed unarmed teen Trayvon Martin could be enormously important or disastrous for either side in Zimmerman's second-degree-murder trial, depending on what a jury determines that it can hear. The Washington Post talked to two experts about their interpretations of the recording.
