James Edward "Pop" Pough (February 16, 1948 – June 18, 1990) was an American spree killer, who, on June 18, 1990, killed nine people and wounded four others in a GMAC (now Ally Financial) car loan office in Jacksonville, Florida, before committing suicide.
The day before, he had killed an innocent woman and man on Jacksonville’s Northside, he wounded two teenagers, and robbed a convenience store.
The shooting at the GMAC office was the deadliest mass shooting committed by a lone gunman in Florida history, surpassing the murder of eight machine shop employees in Hialeah by Carl Robert Brown on August 20, 1982.
