Watch: Was a Virginia firefighter humiliated by co-workers online before she killed herself?
Source: ABC The trolls were horrid to her while she was alive. And they continued to be awful after her death. Fairfax County firefighter Nicole Mittendorff, 31, killed herself in Virginia's Shenandoah National Park, the state medical examiner concluded. But even after the search for her was over, after her body was identified and memorial candles began to burn, the cyberbullies - who claimed they were her fellow firefighters - kept scorching Mittendorff online.
