Update: A 5-year-old boy was at his assigned school all morning, despite earlier reports that he didn't arrive at the school.
David Patton, an Omaha Public Schools spokesman, said the youngster has the same first name as another student in the same grade level.
The second boy's name didn't appear on morning attendance sheets, so the school staff called parents, which is district procedure, Patton said. The staff, however, called the family of the boy who was in class.
After the father said he had put his son on the school bus at 42nd and Erskine Streets, a missing person's call was placed to police. Just before noon, emergency dispatchers announced that police were looking for a boy who has autism.
District officials also began checking with the bus company, which was able to provide video from the bus that showed the boy arriving at Dodge Elementary at 3520 Maplewood Blvd.
About 15 minutes after the missing person's broadcast, dispatchers said the boy had been located.
District officials discovered the fact that they had two students with the same name during their search.
