FILE – In this March 23, 2012 file photo, a Neighborhood Watch warning sign is posted outside The Retreat at Twin Lakes gate in Sanford, Fla. The Retreat at Twin Lakes is where 17-year-old Trayvon Martin was shot and killed by neighborhood watch captain George Zimmerman on Feb. 26, 2012. If Martin’s family sues over his death, they might not target George Zimmerman but the homeowners association of the neighborhood where the shooting happened and Zimmerman lived.
