The single mom knocked out in a vicious Cincinnati street mob attack opened up about the pain and panic attacks she’s endured since the beating — and how she can’t believe she survived it. “I don’t even know how I’m not dead,” the local woman, identified only as Holly, said in a tearful interview Tuesday about being sucker-punched in the brutal, now-viral, caught-on-camera attack. “I should be dead. And so many doctors have been like, ‘You should be dead,’” she said on C-SPAN’s “The Benny Show.” The battered mother said she suffered brain trauma and still has a black eye and bruises on her face as she described the harrowing emotional aftermath of the July 26 beating.
