2. Investigators have not revealed the cause of the explosion. "We are going to identify who is responsible," Avila said.
3. The market was well-stocked for the holidays. "We are obviously in the high season," Tultepec Mayor Armando Portuguez Fuentes said, according to the AP. "There was more product than usual because we are a few days away from Christmas, a few days away from New Year's, and those are the days when the products made here are consumed the most."
