Cathy Welsh lost her son Jeremy to gun violence in 2017 and has been fighting to stop it in her Woodland Hills community ever since. Welsh said hearing that two teenagers lost their lives on Sunday has been heartbreaking. Watch the full story in the video player above. "There's no going back from it. It's so forever and it lasts way longer than the funeral, way longer than the balloon release. It literally lasts forever, it doesn't get easier either you make the space for it or you're stuck in it," Welsh said. Welsh said she has spent the past five years working on ways to stop the violence. She said knowing two more families have to cope with the loss is painful. She said she is hurting for the families of both Jaiden Brown and Mathew Steffy-Ross. "Jaiden lost his family a few years ago to health reasons and it's been her and Jaiden all these years, he was her everything," Welsh said. "And I'm just so concerned, I'm so concerned and Mathew same thing, he was just getting his bearings from losing his own mother and just learning how to live with trauma and grief. And for him to have his life taken, it's literally beyond words. I think it has our community of violence disruptors and healers and community-based organizations literally at a loss right now. Just absorbing this and finding out how we are going to build hope back."Welsh said the Greater Valley Coalition Against violence will hold a meeting Tuesday night to discuss what they can do locally and said they are going to Harrisburg later this month to ask for funding to help.
