MILWAUKEE -- The parents of a Wisconsin National Guard soldier killed in Iraq met Friday morning with the nation's top Guard general in Milwaukee.

Prior to the meeting, Stephen Castner of Cedarburg said that he had hoped to hear an update of an investigation into his son's death from Lt. Gen. Steven Blum.

Blum and Stephen and Kay Castner talked privately at a Wisconsin Air National Guard. Stephen Castner didn't immediately talk about it.

Castner's son, also named Stephen, was killed by a roadside bomb in late July only days after arriving in Iraq. The elder Castner has been pushing the military to investigate what he alleges was inadequate training at Camp Shelby in Mississippi for his son's unit before it was deployed.

Blum, who heads the National Guard Bureau, has said he promised Castner and Gov. Jim Doyle a thorough investigation.

The elder Castner had previously complained to his congressman that the training received by his son's unit was inadequate.

The statement from Blum's office said that Castner's unit "received the best equipment and the best training available anywhere in the world."
