The Christina Grimmie Foundation Stands Ready to Help Borderline Shooting Victims

After 12 people were shot to death at Borderline club, the Christina Grimmie Foundation vows to help.

The families and survivors of mass shootings in the United States are offering help in the wake of yet another tragedy.

"Losing a family member is one of the worst things that anyone can ever go through,"says Marcus Grimmie, the brother of Christina Grimmie, a YouTuber and up-and-coming singer who was gunned down in 2016 as she signed autographs following a performance in Orlando, Florida.

Marcus appears, with other family members of shooting victims, in a new public service announcement for the Christina Grimmie Foundation, a charity established to help the relatives of gun violence.

"Today's latest shooting incident in Thousand Oaks happened very close to home for us here in California," the group posted on its Facebook page Thursday. "Our team is organizing to immediately offer support to the families who have suffered a loss. Your help is needed now more than ever as we shine a light on the needs of these families as we release our new PSA."

Thomas Holgate, now a senior at Marjory Stoneman Douglas High School in Parkland, Florida, survived the carnage in February when former student Nikolas Cruz stormed the campus, killing 17 people and wounding 17 others, authorities said. 

"This is something often forgotten," he says in the new video, "like what happens to the people after the incidents."
