Expert Says Evidence Jibes with Zimmerman's Story

A pathologist hired by the defense says George Zimmerman's account of how he fatally shot Trayvon Martin is consistent with the forensic evidence.

Dr. Vincent Di Maio testified Tuesday that the trajectory of the bullet and gun powder on Martin's body support Zimmerman's version that Martin was on top of him when Zimmerman fired his gun into Martin's chest.

Di Maio says the gun's muzzle was against Martin's clothing and anywhere from two to four inches from Martin's skin.

Zimmerman is pleading not guilty to second-degree murder. He says he shot Martin in self-defense.
