immerman's lawyer, when shown part of the interview being aired Sunday night on Dateline, emphasized that his client would be claiming self-defense.

"I think there were efforts made to render aid to Trayvon," Craig Sonner told NBC's TODAY show.

Mary Cutcher told Dateline that she and her roommate both saw Zimmerman "straddling the body, basically a foot on both sides of Trayvon's body, and his hands pressed on his back."

Cutcher added that Zimmerman told her and her roommate to call the police.

"Zimmerman never turned him over or tried to help him or CPR or anything," Cutcher said.

Sonner also reiterated what he had said in recent days, that Zimmerman suffered a broken nose and a gash to the back of his head.
