Fire tore through a collection of substandard dwellings in Heredia early Wednesday and left 18 families comprised of 68 persons homeless.
Fire fighters attributed the cause of the blaze to a bootlegged electrical system that illegally took current from utility lines. The wind also was called a factor that caused the power lines to arc.
Fire fighters also said that the strong wind helped spread the flames.
There were only two minor medical problems, but the residents fled the flames with very little and appear to have lost nearly all their possessions.
Government agencies are trying to find housing and clothes.
The fire was in the section of Ulloa, Bajos del Virilla. Two homes were leveled as were six of what could best be described as rooming houses. The initial alarm came in at 5:43 a.m.
The bulk of the dwellings were concrete, and wood with tin roofs.
Some 20 of those made homeless are children, said fire fighters.
