LANCASTER COUNTY, Pa. (WHTM) – A mass shooting survivor speaks at Elizabethtown College Thursday evening.

David Hogg was a student at Marjory Stoneman Douglas High School in Parkland, Florida, in 2018 when a former student came in and killed 17 people.

Since then, Hogg has become a well-known gun control activist.

“It’s exhausting to see this happen again and again,” Hogg said. “I think of the families that will never be the same, I think of the families that are still not the same after what happened in Parkland, that are forever changed and damaged. You can’t heal what’s happening with gun violence in America. “Essentially, it’s a scar that stays there forever and it’s left in every single one of those families.”

According to the Gun Violence Archive, there have been 565 mass shootings in the U.S. so far this year.
