My heart goes out to her because the survivor's guilt must be beyond measure, but the stark truth, had she somehow intervened that night, she'd be dead, too. Had she called 911 early, no lives would have been saved. BK brought a deadly weapon that he used fully.
One day, may she take comfort in knowing that, by opening her door, by being able to describe what she saw, by texting her roommates thus locking in an undisputable timeline, she did right by MM, KG, XK and EC. Ultimately may her testimony put BK away for good so that he can do no more harm.
May the rude and unkind element of social media fade away and the kinder, gentler one endure.
The stuff of nightmares, she faced a murderer in the dark of night, and she will have to face him again, in the light of court. He brought her four friends down with a knife. She will bring him down with the truth.
