OSAGE BEACH, Mo. — A fire that broke out at a condo complex in central Missouri killed four children overnight. Two adults were able to escape.

The fire erupted just after 11 p.m. Tuesday at the Compass Pointe condominiums complex in Osage Beach, a community about 177 miles west of St. Louis. The Camden County, Mo., town is a popular tourist destination at the Lake of the Ozarks.

The children were two 2-year-old girls, a 4-year-old girl and a 5-year-old boy, the St. Louis Post-Dispatch reported.

“In my career, about 26 years, we’ve had a few fatalities, but not multiples like this, and of this age,” said Osage Beach Fire Chief Jeffrey R. Dorhauer Sr.

The fire was raging on the top floor, where the children were, and flames were shooting through the roof, Dorhauer told the St. Louis Post-Dispatch.

Firefighters rescued the two adults from a third-floor unit — they weren’t injured — but they had to go through a window to reach the children upstairs because the stairwell had collapsed, Dorhauer said. The children were unresponsive and were later declared dead at a hospital.

Dorhauer said the children were on the fourth floor of the condominium where the fire was the heaviest. The chief said two adults were on the third floor of the condo, but were able to escape.

The cause of the fire is under investigation, but Dorhauer said the state fire marshal hopes to inspect the building later Wednesday when a storm passes out of the region.

“The condition of the building is dangerous,” he said. “So, while we are investigating, we’re hoping to wait for a little sunlight so we can actually see the condition of the building before we do too much.”

Roughly 60 firefighters responded to the scene late Tuesday night.

Dorhauer said he believes the children and adults were permanent residents of Osage Beach and not tourists.
