Tuesday marks the third straight year the families of those victims spread love and compassion to conquer such hate.
April 18 kicks off the third annual "SevenDays," a week full of events in Kansas City meant to make positive change.
"Our focus is helping our own community heal,” said Mindy Corporon, who lost her father, Bill Corporon, and son, Reat Underwood, in the 2014 shooting.
"I think that diversity is the answer,” added Jim LaManno, while speaking with 41 Action News. He lost his wife, Terri, in the shooting.
"If we save one person, we would be doing the community a great service,” he said.
LaManno and Corporon both started their own non-profits, the LaManno-Hastings Family Foundation and the Faith Always Wins Foundation, and together they teamed up to create "SevenDays."
The biggest change to the SevenDays week this year is that the annual walk on the seventh day will be at Union Station.
"We shouldn't just focus on white people in Johnson County that got hurt. We should focus on anyone of any color that is getting, involved in any kind of violence or murders because of their faith or ethnicity,” said Corporon.
Also important to both LaManno and Corporon is pushing for a SevenDays which erases tolerance and brings about compassion for all races, religions and cultures
"I just think that if we have an understanding, we will realize how much more we have in common with one another, our faiths,” said Corporon.
