Yes if her hearing aides were on the bedside stand, she might not have heard the doorbell alert. Mine is quite loud, but I don't know how hearing impaired NG was.But her hearing aids were left behind. If she didn’t sleep with them in then it’s likely she didn’t hear any commotion or a phone alert and was instead confronted with masked men in her room upon stirring. As awful as that is to think about.
Yes the police said she was taken from her bed? So that sounds like she did not hear the front door activity?
