SANFORD, Fla. (AP) — The first police officer to interview George Zimmerman after he shot 17-year-old Trayvon Martin says he didn't yet know that the teen had died.

Officer Doris Singleton said Zimmerman seemed surprised when she told him Martin was dead during an interview at the police station.

"He's dead?!" Singleton recounted Zimmerman saying before he lowered his head.

When asked by defense attorney Mark O'Mara whether Zimmerman showed any anger or ill will in talking about Martin, the officer said "no."

Prosecutors must show that Zimmerman acted with ill will or a depraved mind in order to get a second- degree murder conviction.
