The correct answer is it is messy and looks hastily abandoned.
Mrs. Wright was accused of murdering her husband, and so the police came to her house to investigate. They enter the kitchen and find it very filthy, with dirty rags hanging all over the place, and dishes in the sink still unwashed. They immediately connect the place with Mrs. Wright being a bad housewife and woman in general and don't even try to investigate any further into why she did what she did until the townswomen help them.
