Searchers Monday found the body of a 5-year-old girl in the rubble of an apartment building leveled in an explosion and fire that also injured 17 people at Fort Benjamin Harrison.

The blaze began about 9:20 p.m. Sunday as firefighters and utility workers were investigating a natural gas leak in the Harrison Village housing development.The girl had been listed as missing until her remains were found Monday morning. Sgt. Maj. Ken Harley of the fort's public information office said the victim was the daughter of one of the men injured in the blast. The father was released after hospital treatment, Harley said.

The girl lived in the apartment with her family, Harley said.

Army spokesmen said the blast injured at least 17 people, seven of them critically burned. Hospital officials later downgraded the severity of some patients' injuries to serious. Another 10 people were treated at Hawley Army Community Hospital on the post and released.

Harrison Village is family housing quarters for enlisted soldiers assigned to Fort Harrison, not for any reserve or National Guard forces called up for Operation Desert Shield. The development's 210 families were immediately evacuated following the explosion. They were housed overnight in other military housing on post and in area motels.

The flames burned one four-unit apartment building to the ground and slightly damaged an identical one nearby.
