COMANCHE, Texas -- One person was killed and two others injured in a fireworks explosion at Comanche High School Thursday morning.

According to Comanche police spokesman Marcus Nettleton, the explosion occurred around 9 a.m. as crew were setting up the tubes that house the fireworks for Friday's annual fireworks show.

Nettleton said the dead and injured were local community members and had been helping with the fireworks show for more than 20 years.

Publisher of the Comanche Chief newspaper, James Wilkerson, went to the scene after the explosion. He said when he arrived, he saw two vehicles on fire and the trailer that was holding the fireworks destroyed between the softball and baseball fields at the high school.

As a result, the annual Fourth of July fireworks show, which was scheduled for Friday at Comanche High School, has been cancelled.

The fireworks show at the high school is a 23-year tradition put on by the Kiwanis Club in Comanche. Wilkerson said there were two licensed pyrotechnicians working on the show. A blog post from last year detailed the history of the Comanche fireworks show.
