“We all looked down and we were looking at what apparently was a human foot and leg wrapped in plastic, with cloth wrapped around it, sticking out on top of my father’s casket,” Cleveland's son, Alonzo, told the Daily News.

Cleveland’s relatives were also upset about how the cemetery workers ignored the foot and continued filling the grave.

“They heard it was a leg on the casket and they didn’t even try to investigate it,” Alonzo said.

The family noticed the foot when one of the workers accidentally dropped a pack of cigarettes and his phone into the open grave, relatives said.

When the worker fished out his items with a rake, he saw the limb.

“This is beyond heinous for anyone to witness during their time of grieving over a loved one,” Rev. Kevin McCall, crisis director with the National Action Network, told the Daily News.

He called on New Jersey officials and police to “investigate this despicable act immediately to uncover who is responsible.”
