To Ashley’s insistence, she was left behind as Tom and Barty apparated up to the uppermost levels of the prison. She stepped over a few dead bodies to get to the guard’s desk and searched for the Dursleys’ files. See, she doubted her relatives were placed near the same level as Tom’s inner circle. Child abuse was a very serious thing but in the Ministry’s eyes, it was less than mass murder and torture so Ashley figured that the Dursleys had been placed somewhere around the middle levels. She just had to find out the specific level because she had no plans of looking through every single cell until she found what she came for.
