You already know some of Thomas Prusik-Parkin's reasoning for dressing up like his dead mother, Irene Prusik, for six years to cash her Social Security checks and collect other benefits. During his arrest, he reportedly told authorities, "I held my mother when she was dying and breathed in her last breath, so I am my mother." Then yesterday we learned that this man, now being held in lieu of $1 million bail, kept a casket in his home for undisclosed reasons—though it's safe to assume that's where he'd sleep, all snug and cozy in Irene's nightgown. And now it gets creepier, if that's even possible: According to court papers obtained by the Post, Prusik-Parkin says he was just following Mommy's orders. "She said, 'I will guide you,' he told cops after his arrest Tuesday. "I therefore have had to put on her things and represent the part of me that is her in order to fight for our rights and our home." Aw, a nice young man standing up for his mother's rights; maybe this story isn't so twisted after all!
