A bomb disposal company lost five of its employees in a explosion while working to destroy seized fireworks stored in a old military bunker Friday.

Fire officials said six workers from Donaldson Enterprises, an unexploded ordnance company, were at the Kipapa gulch bunker when the explosion took place.

Saturday Honolulu police and firefighters secured the scene and began removing the two remaining bodies from the wreckage.

Special Services Division from HPD was called in to assist.

Friends and family at the scene Friday and Saturday have identified four of the victims as 29-year-old Justin Kelii, 50-year-old Robert Leahey, 24-year-old Kevin Freeman and 24-year-old Neil Sprankle. Sprankle and Freeman were both graduates of Radford High School.

"They were just these kids that came out and had fun and loved paddling and loved being at the beach," said Sprankle and Freeman's paddling coach and friend, Gino Dayton.

A fifth person, identified as 25- year-old Bryan Cabalce Wahiawa man was critically injured and was rushed to Straub?s burn center, where he died about 6 p.m. Friday.

A sixth worker who suffered only minor injuries refused treatment.

The grandfather of Kelii referred to his grandson as a hardworking explosives technician and said the family worried about his safety.

?He didn?t tell us much, but of course, we were concerned. My wife was really concerned every day,? said George Kelii.
