The news drove people to flock to the tomb of one Marciano Cabillos, who died on May 2, 1994, at the municipal cemetery, to see for themselves how such a "miracle," as they believe, could happen.
The water was described as clear, odorless and tasteless, by those who had the guts to sample it.
The water was reportedly first found flowing out of cracks in the tomb yesterday morning. Residents later decided to bore a small hole on the tombs lower right portion, from where three gallons of the mysterious liquid were said to have been collected.
Reports said some people have got samples of the water, believing it could bring them good luck such as winning in the lotto.
Municipal officials have begun investigating the incident, taking samples of the water for laboratory tests.
Residents believe it is impossible for the water to continue flowing, claiming there is no water outlet or natural well around Cabillos tomb or in the cemetery.
