A historical marker dedicated to Emmett Till has gone missing, adding to the series of previously stolen or vandalized structures dedicated to the boy who was brutally murdered as a 14-year-old in 1955. The news of the latest missing marker, which was located in front of Bryant’s Grocery in Money, Mississippi, comes days after the 66th anniversary of Till's murder, WLBT reports.

The Emmett Till Interpretive Center announced the news on Thursday, saying the sign appears to have been removed after it was hit by a vehicle.

"This week also marks the 66th anniversary of the brutal murder of 14-year-old Emmett Till—an event that helped spark the Civil Rights Movement. It is hard to understand how it can be so difficult to honor the memory of a murdered child—even today," the center tweeted.

The Black teenager from Chicago was abducted from his uncle’s home on Aug. 28, 1955, and killed for allegedly making sexual advances at a white woman. The FBI said Till was leaving Bryant's Grocery with some relatives when he whistled at the store owner’s wife.

After police found Till's body in the Tallahatchie River three days later, investigators said a 75-pound cotton gin had been tied to his neck using barbed wire, causing extensive trauma to the boy's head.

Mamie Till received her son's body in Chicago and insisted on a public funeral with an open casket. She said she wanted the world to see the horrors that were afflicted upon her son.
