MEXICO CITY (AP) 鈥 The head of Mexico鈥檚 春色直播 Immigration Institute will face criminal charges for a fire that killed 40 migrants in a locked cell, the federal Attorney General鈥檚 Office said Tuesday night.

The office said in a statement that the head of the immigration agency, Francisco Gardu帽o, was criminally remiss in not preventing the fire, despite earlier incidents showed the situation at the country's migrant detention centers needed correcting.

Several other officers of the agency will also face charges for failing to carry out their duties, the statement said, but prosecutors did not explain what specific charges or identify the officials.

Prosecutors said the case showed a 鈥減attern of irresponsibility,鈥 their statement released just hours after Mexico's president said two guards seen fleeing when the fire broke out did not have keys to the cell door.

The press office of the immigration agency that Gardu帽o heads did immediately respond to messages and phone calls requesting comment.

Prosecutors said that after a fire at another detention center in the Gulf coast state of Tabasco killed one person and injured 14 in 2020, the immigration agency knew there were problems which needed to be corrected. but alleged they failed to act.

President Andr茅s Manuel L贸pez Obrador's comments about the guards in last month's fire in Ciudad Juarez came on the same day that the bodies of 17 Guatemala migrants and six Hondurans killed in the fire were flown back to their home countries.

It was unclear what effect L贸pez Obrador's comments might have on the trial of the guards, who were detained previously over the fire, which shocked the country.

The guards are seen hurrying away as smoke fills the facility, and they did not appear to make any effort to release the migrants.

Three Mexican immigration officials, a guard and a Venezuelan migrant are being held for investigation in connection with the fire. They face homicide charges.

The migrant allegedly set fire to foam mattresses at the detention center to protest what he apparently thought were plans to move or deport the migrants.

In Guatemala City, relatives of the victims gathered at an air force base with flowers and photos of the deceased to mark their return.

鈥淢y son, my love,鈥 a female voice could be heard calling out, amid sobs from those present as the coffins were unloaded and placed in a line, and relatives were allowed to approach them.

Mexican military planes carried the bodies six migrants to Honduras and 17 to Guatemala. Authorities say 19 of the 40 dead were from Guatemala, but two bodies were still in the process of having their identities confirmed.

An additional 11 Guatemalans were injured in the fire.
