ROSWELL — Authorities are cleaning up the remaining fireworks at a New Mexico storage area where an explosion earlier this week critically injured two firefighters who were moving the material for an upcoming show.

The city of Roswell said Friday that the decommissioning process would result in loud noises and some aerial fireworks being set off. Authorities said heat from Wednesday’s blast potentially damaged the remaining fireworks.

The explosion injured a total of 12 firefighters working at the storage area. Most were treated at the scene for minor injuries, but Jeff Stroble and Robert “Hoby” Bonham are still hospitalized.

Stroble has been with the Roswell Fire Department for 17 years. Bonham has worked for the department for 18 years.

Investigators are still trying to find out what caused the explosion.
