One of those inconsistencies: Zimmerman told police Trayvon had his hand over Zimmerman's mouth during their fight on the night he shot Trayvon.
The Sentinel's source confirmed that Zimmerman's statements include that allegation. But authorities do not believe that happened, the source told the Sentinel, because on one 911 call, someone can be heard screaming for help. If it were Zimmerman, as he claims, his cries were not muffled, the source said.
Zimmerman also told police, the source told the Sentinel, that while the two were on the ground, Trayvon reached for Zimmerman's gun, and the two struggled over it.
Those portions of Zimmerman's account are not corroborated by other evidence, the source said.
