SANFORD, Fla. -

Defense attorneys in the George Zimmerman trial called Sondra Osterman to the witness stand Monday morning.

In tears, Osterman said she knew the screamer in the 911 call recording was her friend and former co-worker "Georgie" Zimmerman. She agreed with the defense's first two witnesses, Gladys Zimmerman and Jorge Meza.

"I hear it," she said. "I hear him."

Osterman is Zimmerman's best friend Mark Osterman's wife. She was the notary who wed Zimmerman and Shellie Zimmerman.

Osterman co-authored a book based on Zimmerman's account. He testified July 2nd for the prosecution and July 8th for the defense.

Prosecutor Bernie de la Rionda asked her about the proceeds of her husband's book. She said the funds were in a savings account and they were going to give the money to Zimmerman after the trial.
