Alleged Zimmerman Claim: Trayvon Put His Hand Over My Mouth, Went for My Gun

George Zimmerman told investigators Trayvon Martin put his hand over Zimmerman's mouth and went for his gun the night of their deadly altercation, the Orlando Sentinel is reporting, according to a source.

The source familiar with the case told the Sentinel that Zimmerman's story hasn't changed in his various statements to police, but that certain details don't quite jibe with what investigators believe what happened.

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.

Zimmerman attorney Mark O'Mara told the Sentinel he hadn't seen his client's statements and therefore could not comment on them. Martin family attorney Benjamin Crump said Zimmerman's two claims -- that he was both screaming in the 911 call and that his mouth was covered -- don't add up.

"It's either one or the other, it can't be both," Crump said. "We have to put together this puzzle because, unfortunately, we don't have Trayvon Martin's version" of events.

Zimmerman is charged with second-degree murder in Martin's death. He is currently free on bail.
