Lead Cop Wanted Zimmerman Arrested

Another twist in the Trayvon Martin case: The chief homicide investigator probing the teenager's shooting wanted to charge George Zimmerman with manslaughter, but was overruled, sources tell ABC. Investigator Chris Serino filed an affidavit on the night of the shooting saying he was not convinced by Zimmerman's claims of self-defense, but the state attorney's office decided there was not enough evidence to make an arrest, the sources say.

As tensions around the case continue to rise, an elderly Florida couple who have no connection to the case have moved out their home after receiving hate mail and unwanted visits from journalists, the Orlando Sentinel reports. The woman's son from a previous marriage is named William George Zimmerman, and their address has been spread on Twitter by people—including actor/director Spike Lee—claiming it is George Zimmerman's home. "To endanger people who are innocent because people are angry is not the answer," their son says. "That's not how we're going to heal. It's not to help the Martin family for someone else to be hurt."
