Trayvon Martin

Defense Witnesses Line Up for Zimmerman

Another testifies he's the one screaming for help


The wife of George Zimmerman's best friend testified Monday that the neighborhood watchman can clearly be heard screaming on a 911 tape that captured the fight between Zimmerman and 17-year-old Trayvon Martin.

Sondra Osterman, wife of Zimmerman's best friend Mark Osterman, told jurors that the screaming voice on the tape was "definitely" that of Zimmerman. 

"Yes, definitely, it's Georgie," Osterman said. "I hear it, I hear him screaming."
