After the cause of the explosion was determined to be natural gas, KKTV 11 News obtained surveillance video showing the explosion in real-time.

The video was taken from a camera at the home and business of Marilyn Henrickson. Henrickson lives right across the street from the Branch Inn, a historic building in Pueblo's Union Avenue Historic District.

The video captures the magnitude of the blast, and the giant dust and debris cloud generated by the blast's force.

Seven people were left injured by the explosion. One 22-year-old woman, Ashley Johnson, died in the blast.
