More than four years after a Florida condominium collapse killed 98 people, federal investigators have yet to make a final determination of the cause.

There has been an update in the investigation into the Surfside condo collapse that occurred three years ago.

Federal investigators of the building collapse that killed 98 people in Surfside announced they expect to release their report in 2026, not next year as planned.

The federal team investigating the Champlain Towers South building in Surfside announced Thursday that they have completed testing at the site and collected data to evaluate the potential causes.

If you worked at or near the site of the building collapse in Surfside, researchers want to examine your toenails.

Video released by a team of federal investigators shows more evidence of extensive corrosion and overcrowded concrete reinforcement in a Miami-area condominium that collapsed in June, killing 98 people.

The National Institute of Standards and Technology held a news conference Wednesday morning to discuss its investigation into the June 24 partial collapse of the Champlain Towers South condominium building.
