Jenkins pleads not guilty to 4 Omaha slayings

OMAHA, Neb. (AP) - A former prison inmate accused of killing four people in Omaha has pleaded not guilty.  Twenty-seven-year-old Nikko Jenkins was arraigned Wednesday morning in Douglas County District Court on four counts of first-degree murder and 10 weapons counts.  Authorities say Jenkins killed all four within a month of leaving prison on July 30. He had served more than a decade for robbery, assault and weapons convictions.  At Jenkins' preliminary hearing Oct. 1, two investigators testified that in September interviews Jenkins confessed to the slayings. They reported that he said voices and commands from an Egyptian god made him to kill the four.  Police have said robbery likely was the motive.
