(Sanford, FL)  --  The wife of George Zimmerman is asking for a divorce.  Shellie Zimmerman filed the paperwork to officially end her marriage to the 29-year-old.  Shellie was in the Florida courtroom throughout her husband's trial on charges that he murdered Trayvon Martin but he did not attend her recent court hearing when she pleaded guilty to perjury.  Shellie Zimmerman said in a TV interview last month that she was considering a divorce but she still wanted to have children and a family.  Earlier this week, George Zimmerman was making headlines after he got a $250 speeding ticket.
