With the George Zimmerman trial underway, people who live inside the neighborhood where Trayvon Martin was shot and killed last year are on high alert, hoping curious visitors won't come to the Retreat at Twin Lakes looking to catch a glimpse of the scene.

Because the case has attracted national and international attention, homeowners inside the neighborhood where the shooting happened said they would not be surprised that people coming to Sanford to watch the trial might want to visit the scene of the scuffle.

"After jury selection, people are going to be swarming through here," said Frank Taaffe, who referred to himself as a fellow neighborhood watch volunteer in the same neighborhood. "This is where it all happened. This is ground zero, man."

Taaffe, who let us into the gated community, said he believes people will try to see where the actual shooting happened, near the neighborhood's clubhouse.

Both the clubhouse and the entire neighborhood are being patrolled by Sanford police during the Zimmerman trial, and homeowners have been told to call police if they spot anyone who does not live there in the neighborhood.

The latest security addition to the subdivision is a fence erected to keep anyone who does not belong here out.

"If the fence had been put up, we wouldn't be here talking today," said Taaffe, who believes the shooting would never have happened if the fence had been in place then.

Taaffe has previously said he supports Zimmerman, and believes he did the right thing.

Other homeowners asked us not to record video of them, and we respected their wishes.

Meanwhile, Andre Klass, the head of the subdivision's social committee, said Wednesday the community's neighborhood watch program was permantly suspended last year following Martin's death.

In his email, Klass also said Taaffe does not have any official involvement with the Retreat of Twin Lakes Homeowners Association and has been in foreclosure proceedings since before the incident.
