You may be interested to read the probable cause affidavit for Shellie Zimmerman's arrest (courtesy of ThinkProgress), which details how she accessed the money George Zimmerman had raised:
Original: Things are not going well for the Zimmerman family: After a judge revoked George Zimmerman's bail on June 1, his wife Shellie Zimmerman was arrested on Tuesday for perjuring herself during his original bail hearing. Sheriff's deputies booked her into jail in Seminole County, where she was posting her $1,000 bond when they announced her arrest. It all goes back to her testimony on April 20, when she said the couple had no money, even though George Zimmerman had been collecting donations through his now-defunct website, therealgeorgezimmerman.com, where he raised $204,000 to defend himself against second-degree murder charges in the killing of Trayvon Martin.
