Anita Belle Nicky Horvitz, 63, was shot and killed at her home in suburban Pittsburgh on April 28, 2000.

That attack was the opening act of a multi-location, racially motivated rampage across two counties. Baumhammers proceeded to fire into the synagogue where Horvitz was a member, spray-painted swastikas and the word Jew on its facade, and went on to kill several other people of South Asian, East Asian, and African American descent before being arrested that same day in Ambridge. He was charged with multiple counts including first-degree murder, attempted homicide, ethnic intimidation, and arson.

At trial prosecutors presented material they said showed white supremacist motivation, including a manifesto Baumhammers authored calling for an end to non-white immigration. After psychiatrists evaluated him, he was found competent to stand trial; in May 2001 a jury convicted him on all charges and recommended the death penalty. Anyone who knew Anita Horvitz or saw her in the neighborhood around April 28, 2000 is asked to come forward with information.
