A vacant building in North St. Louis collapsed onto an adjacent home Sunday evening, trapping two children inside. A 16-year-old boy managed to pull his 4-year-old nephew to safety before

Fire officials say the collapse was possibly triggered by heavy rains.

A mess of furniture and cinderblocks remains exposed to the open air right alongside the the Quinnipiac River a week after a back wall collapsed at a Front Street warehouse that may soon be built up into new apartments and retail space.

The warning comes after two people lost their lives while four others sustained injuries during the collapses that occurred in Nairobi and Kericho counties.
