It has been destroyed several times over the years and in a few months the shield will be replaced again – this time with a bullet-proof marker.
The shield was placed near the spot where Till's body was pulled from the Tallahatchie River in 1955. The 14-year-old African American was tortured and killed by two white men after he was accused of flirting with a white woman. His death became an important trigger for the civil rights movement.
"For 50 years, our church did not want to talk about Emmett Till, they just wanted to forget it," said Weems.
The students were suspended by their brotherhood, and the Department of Civil Rights's Department of Justice is also reportedly investigating.
It's not the first time the shield sees any problems.
The first sign was affixed along the river in 2007 and was stolen the following year. There have never been any arrests. When the marker was replaced, it was littered with bullet holes. In 2018, a third sign was posted at the site, but only 35 days passed before it was shot at again.
According to Matt, the shield will be replaced in October by a 600-pound reinforced steel shield Dilling, founder of the Brooklyn-based Lite Brite Neon Studios, who worked to create the shield.
And this time the shield should be bulletproof.
"We will not stop there will be another sign," said Rev. Willie Williams, treasurer of the commission. "This particular area will progress in the long run, and because of this heritage and history, it is much bigger than any of us."
The Commission calls on local authorities to initiate an investigation of the student photo. The members said they did not know if the students had damaged the sign.
When Weems walked around the remote spot where the marker stood on Friday, the destroyed signs brought him both frustration and hope.
"And the hope is that there are people in this country who care about this story," Weems said. "This Emmett Till did not die in vain, his mother did not allow him to die in vain, and we have a sacred oath to make sure these sites work again."
