"Attack of the Mannequins" might sound like a horror film title, but one woman insists it could be a documentary. Diana Newton of Westminster (Orange County) sued J.C. Penney Co. Inc. last month after being thwacked on the head by a department store dummy. The 51-year-old said she was ambushed by a legless female mannequin at the Westminster Mall, an altercation that left her with a bloodied scalp, a cracked tooth, recurring shoulder pain and numbness in her fingers. Most of the cases involve mannequins toppling over onto customers, but an Indiana woman said she caught herpes from the lips of an American Red Cross CPR training dummy. When a clerk tried to remove the garment, the dummy's arm flew off and struck Newton's head, according to her lawsuit filed in Orange County Superior Court.
