OMAHA, Neb. -- Officials say the body of a 7-year-old Brazilian boy missing for nearly two years and believed to have been killed with his parents in Nebraska has been pulled from the Missouri River.

Omaha Police Chief Alex Hayes and Douglas County Attorney Don Kleine announced the discovery Tuesday.

Omaha station KETV reports that a dive team pulled Christopher Szczepanik's remains from the river last week. It took several days for DNA tests to confirm the identity.

Three men were charged with murder in the family's deaths, although the bodies hadn't been found. The parents' bodies still haven't been recovered.

Investigators say the men worked for the Szczepaniks. The family was living in Omaha while the father worked renovating a former school. They were last heard from in December 2010.
