George Zimmerman wears bulletproof vest in public, lawyer says

George Zimmerman, the neighborhood watch volunteer who fatally shot Miami teenager Trayvon Martin last year, wears a disguise and a bulletproof vest whenever he is in public, his attorney said.

"He never feels safe," attorney Mark O'Mara told FoxNews.com. "His security has been cut and he stays inside his secure location all day long due to threats."

As a result of the confinement, Zimmerman's health has taken a turn for the worse, O'Mara said. He gained about 100 pounds in six months and is stressed about the threats and his upcoming murder trial, which is set to begin on June 10.

"If I was confined to four rooms all day, I bet I'd gain a lot of weight, too," O'Mara said.

Zimmerman has been charged with second-degree murder in the shooting death of Martin but has pleaded not guilty.  He claims he acted in self-defense, saying Martin attacked him.

O'Mara said he talks with Zimmerman every day. He said the couple relies on donations to survive since neither one can hold down a job.

He said Zimmerman, who previously aspired to be a judge, looks forward to the trial to begin, but has been disenfranchised about the legal proceedings thus far.

To be sure, even if his client is acquitted, O'Mara said he will likely never feel safe in his hometown or Florida.

"He'd have to go somewhere where nobody knows him," O'Mara said.
