The family rescued by George Zimmerman when they were trapped in an overturned SUV canceled a scheduled news conference today and is pleading for privacy.

Zimmerman was one of two men who came to the aid of Dana and Mark Gerstle and their two children, who were trapped inside a blue Ford Explorer SUV that had rolled over after traveling off the highway in Sanford, Fla., about 5:45 p.m. Thursday, the Seminole County Sheriff's Office said in a statement.

The Gerstles were expected to hold a press conference today at the office of Zimmerman's attorney Mark O'Mara, but cancelled a few hours before it was supposed to take place.
