After refusing to answer questions posed by a visiting mental health worker, Marcus Allen Smith barked in defiance as she walked away. "I'll kill you like I killed the old lady," Smith shouted from his cell at the El Paso County jail, adding a confession to the raft of physical evidence tying him to the November 2011 killing of 87-year-old Kathryn "Kit" Grazioli. Details about the January 2014 confession were heard in court Monday as the prosecution case drew to a close on what would have been Grazioli's 92nd birthday.
