Fort Riley ? A soldier serving in Iraq was returning to Fort Riley after his 9-year-old daughter died in a fire at his family’s apartment.

The girl’s mother and three younger siblings – ages 5, 6 and 16 months – escaped the fire, which was reported about midnight Monday at the Colyer Manor East.

No names were released and the cause of the fire was under investigation, officials said Tuesday.

“Our main effort and our main focus right now is on that mother and her three children … and also bringing that service member back from Iraq so that he can link up with his family members,” Fort Riley Garrison Commander Col. Richard Piscal said.

The girl’s father is a member of the 1st Battalion, 28th Infantry Regiment, 4th Infantry Brigade Combat Team, 1st Infantry Division.

Crews from the Fort Riley Fire Department responded to the fire after neighbors called it in, said Chris Ferris, Fort Riley’s director of emergency services. The girl was pronounced dead shortly after arriving at Irwin Army Community Hospital.

The seven remaining apartments in the building were structurally safe, said Brian Beauregard, Picerne Military Housing program director.

The Colyer Manor homes are among the first that Picerne Military Housing plans to demolish as part of new development of on-post housing. Picerne will survey the damage before deciding what to do with the two-story, eight-plex home, Beauregard said.
