A 43-year-old Kansas man allegedly spent his Christmas Eve on a mission to kill someone and armed himself with a hammer before knocking on a door of a home with several cars in the driveway. When a woman holding her 1-month-old baby answered, the suspect — later identified as Jason Eastburn — pounced, cops say. He repeatedly hit her in the head with the hammer, requiring doctors to patch up the wound on her head with four staples, according to a probable cause arrest affidavit released on Monday.
