POLICE: Zimmerman Said 'That Doesn't Even Sound Like Me' Screaming For Help

During George Zimmerman's second-degree murder trial, a lead police detective testified that Zimmerman initially said a voice screaming for help on a 911 call didn't sound like his own.

The defense played the recorded call, placed by a neighbor moments before Zimmerman killed Trayvon Martin, multiple times in court. The audio contains a fight, with one man screaming for help. Zimmerman claims self-defense, so if jurors believe it's him, he could win the case.

When lead detective for the Sanford, Fla. police department Chris Serino played the recording for Zimmerman during questioning, Zimmerman said, "That doesn't even sound like me," Serino told jurors Monday.

Mark O'Mara, lead attorney for the defense then asked Serino if he thought Zimmerman was in denial.

"I didn't take it as denial. I took it as not recognizing his own voice," Serino said.

In a Fox News interview last year, however, Zimmerman said he was yelling for help as 17-year-old Trayvon Martin slammed his head into the concrete.

Multiple other witnesses, either friends, family, or co-workers of Zimmerman, have also testified the voice screaming for help does belong to Zimmerman. On the other hand, both Martin's mother and brother claim they hear Martin's voice on the recording.
