Overview

• The ATF National Response Team is processing the scene, with hazardous residues and secondary detonations restricting access and delaying Tennessee OSHA's on-site work.
• The Tennessee Bureau of Investigation has begun a second round of rapid DNA comparisons on site using family reference samples.
• Authorities list 16 people unaccounted for and presume them dead, as communities hold vigils and families seek direct updates from officials.
• Emergency management crews are disposing of unstable materials at the facility, which may produce audible blasts and visible smoke during operations.
• The explosion destroyed much of the complex and was detected as a magnitude 1.6 seismic event about 50 miles west of Nashville.
