Tultepec - Some brought photos of their missing loved ones to the Mexican fireworks market where a series of explosions killed at least 33 people, while others who had already claimed their dead began to mourn their loss.
Friends and relatives of Ernesto Ornelas, 67, gathered in the narrow street in front of his house in the Mexico City suburb of Naucalpan late on Wednesday to pray, sing and mourn his loss in the deadly blasts, whose cause has still not been determined.
Authorities in Mexico State said the death toll could rise further because 12 people were listed as missing and some body parts were found at the scene of Tuesday's tragedy in the San Pablito fireworks market.
Ornelas had been shopping for fireworks with his son Cesar Ornelas and his 15-year-old grandson Francisco when the explosions occurred. They became separated in their dash to escape. Cesar and Francisco suffered minor injuries and only later saw Ernesto, bleeding from his head and with his clothing burned, loaded into an ambulance.
After learning which hospital he'd been taken to they were told he had died of a head injury, Cesar Ornelas said: "We don't know if it was from a fall or if a flying rock hit him."
Investigators were focusing their attention on ignored safety measures that led to vendors displaying fireworks outside their concrete stalls in the passageways that divided the sellers. The passageways were supposed to prevent exactly the sort of devastating chain reaction that occurred.
Of the 33 dead, the state listed 10 as unidentified. In some cases, the bodies were so badly burned that DNA identification will be necessary.
San Pablito was especially well stocked for the holidays and bustling with hundreds of shoppers when the blast reduced the market to a stark expanse of ash, rubble and the scorched metal.
Video and photos of the stalls from previous years showed concrete-block enclosures with open dirt passageways between them...later photos showed the passageways filling up with fireworks and awnings.
Deadly fireworks explosions have also occurred elsewhere in Mexico: In 2002, a blast at a market in the Gulf coast city of Veracruz killed 29; in 1999, 63 people died when an explosion of illegally stored fireworks destroyed part of the city of Celaya; in 1988, a fireworks blast in Mexico City's La Merced market killed at least 68 and in 2013 a rocket struck a truck loaded with fireworks for a religious procession in Tlaxcala state, killing 17 people.
