Manuel Oliver and Patricia Padauy-Oliver’s son Joaquin Oliver was killed in the 2018 Parkland, Florida school shooting. In honor of what should have been Joaquin’s 23rd birthday, his parents and other activists visited 23 cities impacted by gun violence on “Guac’s Magical Tour Against Gun Violence.”

We joined Manuel and Patricia throughout the tour to hear about how they’re channeling their loss into inspiring change.
