FLINT, Mich. -- One of the most moving moments from Sunday night’s debate came when the candidates heard from the father of 14-year-old Abigail Kopf, who was injured in last month’s mass shooting in Kalamazoo.

He wanted to know what they will do to address the problem of mass shootings in the U.S.

And don’t say tougher mental health laws, he said.

“We should try everything that works,” former Secretary of State Hillary Clinton said, adding that the Brady Bill has been working to prevent shootings and making gun manufacturers accountable. She noted that U.S. Sen. Bernie Sanders of Vermont opposed it.

Sanders said instant background checks should be expanded, adding: “To be honest, nobody has a magic solution to this problem; for us to tell you” that they “absolutely will not happen again is not true.”

Six people were killed and two others were injured in a series of random shootings in Kalamazoo County, Mich. on Feb 20. Police say 45-year-old Jason Dalton, who was working as an Uber driver that evening, shot Abigail and four women at a Cracker Barrel restaurant. Only Abigail, who was shot in the head, survived the attack. Authorities say Dalton also killed two other victims and wounded another in two separate shootings that evening.

Kopf said his daughter, who was critically injured, is on the mend. “She’s laughing, giggling, but has a long road to physical recovery.”
