"Here, I had finally found peace and safe harbor," Renee Good's wife wrote. "That has been taken from me forever."

The wife of the woman shot and killed by a federal immigration officer in Minneapolis says the couple had stopped their car to support their neighbors and they had whistles, while the masked agents had guns.

A woman who identified herself as the deceased's mother identified her as Renee Nicole Good. Sen. Tina Smith, D-Minn., called Good “a U.S. citizen, a mother, and a Twin Cities resident.”

Local officials accuse immigration agents of "recklessly using power", as federal authorities say the officer fired shots in self-defence.
