Just weeks after the tragedy, Kaleka was contacted by a former white supremacist who wanted to meet up and do something to prevent further violence. Though initially unsure, Kaleka eventually did meet with Arno Michaelis (above right), a 42-year-old former white supremacist who says he contributed so extensively to the movement that he may have influenced the shooter in someway.

Kaleka wanted his dad’s memory to be a force for peace and believes that Michaelis’ story proves people can turn away from a life of hate. One and a half years later, Kaleka and Michaelis together run Serve2Unite, a community group to counter violence with peace.
