The tears from a statue of the Virgin Mary that is apparently weeping are composed of olive oil, chemical analysis has concluded. However, diocesan authorities have yet to establish where the oil is coming from.

The Diocese of Las Cruces has been investigating that statue at Our Lady of Guadalupe church in Hobbs, New Mexico since May, when visitors reported seeing a liquid flowing from its eyes.

Bishop Oscar Cantu told Las Cruces Sun-News that a sample of the fluid had been sent of scientific analysis. “And we determined it was olive oil, a scented olive oil,” he said.
