Services have been scheduled for Thursday afternoon for Sgt. Deyson K. Cariaga, the first Hawai'i National Guard soldier to die in Iraq.

The service will be 6 p.m. in the Mission Memorial Auditorium at 560 South King St., which is diamondhead of Honolulu Hale.

Cariaga, 20, of Kalihi, died July 8, halfway through a one-year deployment. The 2002 graduate of Roosevelt High School was driving the third of seven Humvees on a beat-up asphalt road when a 155 mm artillery shell exploded beneath the vehicle. Three Air Force troops also were injured in the explosion on the road, which soldiers call "IED Alley" — after the military term for roadside bombs.

Cariaga, who was serving with the 229th Military Intelligence Company, 29th Brigade Combat Team, took the brunt of the blast and was killed instantly. He was posthumously promoted to sergeant.

Mission Memorial Auditorium will open to the public at 5 p.m., one hour before the service. A closed-circuit feed will transmit the service to those outside.

Parking after 5 p.m. is available at the Honolulu Municipal parking lot off King Street. 'Iolani Palace parking opens at 6 p.m.

Civilian dress is aloha wear; military members are asked to wear Class A or its equivalent.

In a smaller ceremony that will not be open to the general public, Cariaga's ashes will be interred Friday morning at National Memorial Cemetery of the Pacific.

Cariaga's survivors include his mother, Theresa Inouye, and an older brother, Lance Cariaga.
