Invisible Children of San Diego that helps child soldiers, identified the dead American as Nate Henn, who was killed on the rugby field. The group says Henn studied psychology at the University of Delaware, where he also played rugby.
Jason Vanterpool, who played rugby with Henn, says Henn got along with everyone and was always smiling. He says Henn only played the sport for about a semester and a half due to an injury.
Henn was among at least 64 people killed when explosions tore through crowds watching the World Cup final at a rugby club and an Ethiopian restaurant. Police feared an al-Qaida-linked Somali militant group was behind the attacks.
