SANFORD, Fla. -

Supporters of Trayvon Martin are taking to social media, urging users to make a statement before the jury reaches a verdict.

Facebook users who say they are seeking justice on behalf of Martin are displaying a black box in place of their profile picture as a show of support.  Many are also posting an explanation, saying, "I am blacking out my profile pic for Trayvon Martin and the countless non-famous people who die from senseless violence everyday."

Meanwhile, tweets have popped up that claim to have the address of George Zimmerman, who's charged with murder in Martin's death.  The tweets seem to encourage violence, something Sanford police say they're prepared for but not expecting.

Police told Local 6 they have a team monitoring social media, assuring the public they will keep the peace.

"We anticipate the verdict to be peaceful.  We anticipate people to accept the verdict," Sanford Police Chief Cecil Smith said.

Smith added that things have remained calm in the city throughout the trial.

"The citizens of Sanford have said, 'We've been through this, we've asked for things to happen and now we want the judicial system to run it's course peacefully,'" Smith said.

A spokeswoman for the Seminole County Sheriff's Office told Local 6 that they also have a plan in place to respond to any potential violence.

Closing arguments were delivered on Thursday and Friday, and the jury will begin deliberations later.
