Two teenage girls in a same-sex relationship in the US have found with gunshot wounds to the head in a south Texas park, with one of them dying from her injuries, MSNBC reports.

Mollie Judith Olgin, 19, and Mary Christine Chapa, 18, were found in knee-deep grass in a nature area in the suburb of Portland by a couple on Saturday, according to Portland Police chief Randy Wright.

Police are searching for their assailants.

Olgin died of her injuries, while Sinton was rushed to a hospital where she had surgery and was in serious but stable condition on Sunday, local television reports said.

The girls had been together five months, according to friends.

When asked if police had been able to determine if the girls’ sexuality played any role in the shootings, Wright told MSNBC that it was something they were looking at but had been yet to establish a motive behind the attack.

“If we had a name, you know, we’d be having a different conversation right now. But we have not been able to gather enough information to identify a suspect yet,” he said.

“It appears as if… this was not just a random attack but that’s something that we really have to develop over time.”

Wright said police had recovered a bullet casing from a large-caliber gun at the scene, but they haven’t found the weapon. A resident living nearby reported hearing two loud bangs Friday before midnight but believed they were from firecrackers, the Corpus Christi Caller Times newspaper said.
