A video of four seventh-grade boys mercilessly taunting a 68-year-old bus monitor in New York state that went viral has turned the victim into an international fundraising juggernaut and opened her tormentors to an onslaught of threats and abuse.

From around the world, small donations for Karen Klein poured into the crowd-funding site indiegogo.com, at one point crashing the site and pulling in a staggering $443,057 by early Friday.

At the same time, police in the Rochester suburb of Greece, N.Y., were stepping up patrols around the houses of the middle-schoolers accused of taunting her. Police didn't name the boys but their purported identities leaked out on the Web.
