Elaine and David McClain are in their 70s and say they have a son named William George Zimmerman who lived in their Sanford-area home in the mid-1990s. They say he is no relation to 28-year-old George Zimmerman who killed 17-year-old Trayvon Martin on Feb. 26.
The killing has touched off widespread public outrage and protests across the country, including from Lee and other celebrities, because Zimmerman was not arrested. He says he acted in self-defense.
Lee tweeted late Wednesday: "I Deeply Apologize To The McClain Family For Retweeting Their Address. It Was A Mistake. Please Leave The McClain's In Peace."
