The widow of a Harvard-trained entrepreneur who was gunned down outside a suburban Atlanta preschool is set to appear in court.

Andrea Sneiderman faces scheduled arraignment Monday morning. She is accused by authorities of conspiring with her former boss, Hemy Neuman, to kill her husband, Russell "Rusty" Sneiderman. He was slain moments after dropping off the couple's son at the preschool in a wealthy Atlanta suburb in November 2010.

Neuman was found guilty but mentally ill at trial and then sentenced last March to life in prison. Days of testimony at that trial focused on whether Andrea Sneiderman was involved in an affair with Neuman and whether she knew details of her husband's death suspiciously early.

Andrea Sneiderman has repeatedly denied an affair and also denied knowing anything about the shooting.
