SANFORD, Fla. -

Sanford city officials said on Wednesday that security preparations are under way as special prosecutor Angela Corey holds a news conference in the Trayvon Martin shooting death investigation.

County officials said the Emergency Operations Center is at a level 2 alert, meaning the center is minimally staffed -- but at all times. Sanford Mayor Jeff Triplett said the EOC and additional authorities are on standby.

"You always have that concern in the back of your head for the 'what-if' we don't know one way or another," Triplett said. "But you know we stand ready for the 'what-ifs' and everything up to the point has been peaceful, the point's been made and it's in someone else's hands now, it's in her [Angela Corey] hands now and we're ready."

Meanwhile, reports have surfaced about George Zimmerman being charged in Martin's death, citing a law enforcement official. It's not clear if Corey's news conference is in regards to an arrest.

The case has garnered national attention because George Zimmerman,  the neighborhood watch leader who shot Martin in late February, has not been arrested or charged.

"We're prepared for any situation, we know there will be some emotional responses from the community, we just want to make sure everybody remains calm," said Lisa Mosca of the city of Sanford.

Media outlets from across the country have flocked to Sanford, prompting deputies to put metal barriers around the intake area of the John E. Polk Correctional Facility in Seminole County.

Officials said the barriers, which were installed Wednesday, are a precautionary measure because national media has been camping out there.

Sanford Mayor Jeff Triplett said city officials have met with the Department of Justice multiple times to develop a security plan. He said the city is also consulting other cities, such as Miami and New York, to see how those cities are preparing for the news.

Meanwhile, Zimmerman's attorneys, Hal Uhrig and Craig Sonner, stepped down from the case Tuesday, saying they haven't heard from Zimmerman since Sunday. Martin's family responded by saying they more worried now because Zimmerman is unreachable.
