What Goes Around Comes Around
I n 1883 Texan Henry Ziegland jilted his girlfriend. Grief stricken she killed herself. Her brother writhing with hatred tried to avenge her senseless death by shooting Ziegland.
The bullet grazed his face and embedded itself deep within a tree. Ziegland fainted and the brother thinking he had completed his mission killed himself.
Ziegland lived and in 1913 was clearing his land and wanted to remove the tree with the bullet in it. It was too hard to cut the tree down so Ziegland used dynamite. When the tree exploded the blast sent the bullet through Ziegland's head and killed him.
