Mrs Mullins and her husband, Edwin Mullins, lived at 4351 Wisteria Lane. Her husband was a taxidermist, and kept a lot of stuffed animals in his home, as revealed by Susan, who also states that he often invites people in, and then introduces them to all his “pets”. They also had a problem with teenagers spreading toilet paper across their yard, and kept a spare key to Mrs. McCluskey’s house. They also trusted Bree by giving her a key to their home.
They left Wisteria Lane because of all the action happening there: murder, suicide, blackmail, violence, and arson. It was never determined where they went. Their house was purchased, sight unseen, by the Applewhite family.
