Minutes after Missouri executed Marcellus “Khaliifah” Williams on Tuesday, his son, Marcellus Williams Jr., addressed a crowd of supporters that had gathered to grieve in front of the state prison in Bonne Terre.

Among them was Maha Odah, a Palestinian American activist with Al-Hadaf Kansas City, a Palestinian liberation organization, who had driven more than two hours to be there. When Williams Jr. began to grieve for his son’s stolen opportunity to know his grandfather, Odah thought of her own experience with loss.

“I saw a mirror,” Odah said, recalling moments spent with Williams’s family. “A reflection of these two systems that are both upheld by the U.S. that condemn Black and Palestinian men, our fathers, our grandfathers, and the rest of our families, at the mercy of those who continue to find ways to dehumanize us.”
