Maupin was honored on Saturday by hundreds of mourners who lined the Cincinnati streets with American flags as a police procession led his casket to a memorial service.
The 20-year-old was captured in April 2004, when insurgents attacked his fuel convoy. The convoy was part of the Bartonville, Illinois-based 724th Transportation Company.
Maupin's remains were found last month northwest of Baghdad, about 12 miles from the site of the ambush.
