Hundreds of Catholic faithful come together Sunday night near Pemex's battered Mexico City skyscraper to pray for the victims of a deadly blast at the site.
The explosion at the oil giant's headquarters killed at least 36 people and injured 121 others.
One more person is still reported missing.
Grieving Pemex employees joined relatives of their colleagues lost in the blast, keeping a united front in the face of tragedy.
(SOUNDBITE) (Spanish) FRANCISCO JAVIER, SAYING:
"My daughter-in-law died. She was in human resources. She died in this blast and I'm here to support my people. Here we were born; here we grew up, all petroleum workers."
Rescue workers had been digging through the last sections of the building's basement and could soon call off their search.
Speculation over the cause of the blast has ranged from a bomb attack, to a gas leak, to a boiler blowing up.
Mexico's government has vowed to find out whether the explosion was a deliberate attack or another stain on the company's poor safety record.
