HERMOSILLO, Mexico (AP) – Sobbing relatives waited outside a morgue yesterday to claim the bodies of 35 children killed in a day care fire in northern Mexico despite desperate attempts to evacuate babies and toddlers through the building’s only working exit. One father crashed his pickup truck through the wall to rescue his child.

One family buried two-year-old Maria Magdalena Millan, dropping white roses onto her tiny coffin and attaching a Dora the Explorer balloon to the cross marking her grave.

“I love you and I don’t want to leave you here!” her mother screamed.

Delfina Ruelas, 60, said her grandchild German Leon died of his burns Saturday morning, three days after his fourth birthday. She and her husband saw television news reports that the ABC day care was on fire Friday and rushed over that evening.

“I thought he wasn’t that burned and that we would find him OK, but he was very burned,” said Ruelas, dissolving into tears outside the morgue in the northern city of Hermosillo, where she waited along with 30 other relatives. “They operated on him yesterday, and he held on, but today he couldn’t hold on.”

Firefighters carried injured children through the front door – the building’s only working exit – and through large holes that a civilian knocked into the walls before rescue crews arrived, according to a fire department official who spoke on condition of anonymity because he was not authorised to speak publicly about the fire.

Noe Velasquez, an employee at a nearby auto parts store who helped pull out five toddlers, said the father of one of the children rammed his pickup truck through a wall. Velasquez did not know if the man’s child survived.

“I didn’t sleep last night. I’ve never gone through anything like that in all my life,” he said.

The tragedy once again raised questions about building safety in Mexico: Officials cracked down on code violations following a deadly stampede at a nightclub last year and a fire at a disco nine years ago.

A May 26 inspection found that the day care building – a converted warehouse with a few windows mounted high up – complied with safety standards, said Daniel Karam, the director of Mexico’s Social Security Institute, which outsourced services to the privately run day care.

Asked if the single functioning exit constituted a safety code violation, Karam only repeated that the building had passed the inspection, although he conceded that the security requirements might have to be re-evaluated.

“We always have to be open to improvements, especially when we have a tragedy that has so moved us,” Karam said.
