Emmett Louis Till (1941–1955) was a 14-year-old African American boy who was abducted and murdered in Mississippi after being accused of flirting with Carolyn Bryant, a white store owner’s wife. His lynching became a national story when his mother, Mamie Till-Mobley, insisted on an open-casket funeral so the world could witness the brutal violence inflicted on her son.

For a more detailed account, Wikipedia provides a good summary.

He was buried in Burr Oak Cemetery on Chicago’s South Side. When a friend and I visited the cemetery the day after a rainstorm, the grounds were waterlogged and poorly drained. We were unable to approach his grave without wading through several inches of standing water. It is unfortunate that the cemetery contends with this issue, as my friend and I visited several other cemeteries that day, none of which had significant standing water.
