Dog mourns fallen Navy SEAL

Labrador retriever Hawkeye, with a heaving sigh, lays by the casket of his owner, Navy SEAL Jon Tumilson, during the funeral at the Rudd-Rockford-Marble Rock Community School on Aug. 19 in Rockford, Iowa.

Tumilson was one of 38 killed on Aug. 6 when a rocket-propelled grenade took out a U.S. Chinook helicopter in Afghanistan.
