3:43 p.m. ET: Zimmerman said he felt light-headed in the back of the patrol car, according to Smith.
3:38 p.m. ET: On the way to the patrol car, Smith says Zimmerman told him something voluntarily:
"He stated to me that he was yelling for 'help' and that nobody would come help him," said Smith.
Zimmerman said it again once they got to the car.
"It was almost confusion. Sort of a confused look on his face," said Smith.
3:36 p.m. ET: Once Zimmerman was handcuffed, Smith says he secured Zimmerman's gun.
"Did he seem angry?" asked O'Mara.
"No, sir," said Smith.
"Did he seem frustrated?" asked O'Mara.
"No, sir," said Smith.
"Did he seem spiteful of anything that was going on?" asked O'Mara.
"No, sir," said Smith.
"Any ill will or hatred at all when you first saw him moments after the event?" asked O'Mara.
"No, sir," said Smith.
Smith also says Zimmerman's behavior didn't seem strange and he didn't seem cavalier.
