This week in neighboring Sonora, firefighters and their supporters are marching to protest what they consider unjust convictions related to a 2009 day care fire that killed dozens of children.

It’s been more than 12 years since the ABC day care in Hermosillo that left 49 children dead and many others with lifelong injuries.

Earlier this year, Mexico’s supreme court upheld the convictions of 22 people considered responsible for the fire. Among them, five firefighters.

But many are now pushing back against penalties for firefighters after one of the five released a video last week in his defense.

In the video Arturo Davila says his only connection to the case was signing off on a blueprint in 2001 when he oversaw building inspections.

Many of the convictions are related to the lack of proper safety measures at the day care.

Protesters say firefighters are the ones who risked their lives to save as many children as possible, and should not be among those punished.

However, some parents of children killed in the fire have spoken out in opposition to the march, calling it offensive and misguided.

One mother, whose son died at the ABC daycare, wrote a message on social saying that the tragedy that killed 25 girls and 24 boys was only possible because of the many people who failed to fully do their jobs and ensure that the daycare was a safe place for children.

"Don't be confused," she wrote. "The firemen who were convicted in the ABC daycare case, it is not because they couldn't rescue all the children from the fire, but because of the authorization they gave for that building to begin operating. Don't try to make victims of those responsible for this tragic crime whose only victims were my son and his friends, dead and injured."
