PORTLAND, Texas -- Two teenage girls in a relationship were found with gunshot wounds to the head in a south Texas park, with one of them dying from her injuries, media reports say. Police were searching for the gunman.

Mollie Judith Olgin, 19, and Mary Christine Chapa, 18, were found in knee-deep grass in a park in Portland by a couple early Saturday, the Corpus Christi Caller Times said, citing Portland Police Chief Randy Wright.

Olgin, of Flour Bluff, died; Chapa, of Sinton, was rushed to a hospital where she had surgery and was in serious but stable condition on Sunday.
