After a U.S. Immigrations and Customs Enforcement officer shot and killed Renee Nicole Good in Minneapolis last week, rival GoFundMe campaigns emerged. One raised $1.5 million for the family of the slain mother of three. Another has pulled in nearly half a million dollars for Jonathan Ross — the ICE agent who killed her.

Among the donors to the Ross GoFundMe was billionaire hedge fund manager Bill Ackman, who shared a post about the fundraiser on Saturday and donated $10,000.

The fundraising campaign for Ross was created by an account using the name of Clyde Emmons, of Michigan. Other online accounts, linked to the GoFundMe and bearing the same name, posted white supremacist imagery and called Good “a stupod bitch who got what she deserved.”
