Two Texan teens in a lesbian relationship have been found shot in the head, with one dead and the other hospitalised.

19-year-old Mollie Olgin and 18-year-old Mary Chapa were found in knee-deep grass at a park in Portland at 9am on Saturday, Police Chief Randy Wright said.

Olgin died of her injuries, but Chapa was rushed to hospital for emergency surgery and is currently in a stable condition, Wright said.

When asked if police had been able to determine if the girls’ sexuality played any role in the shootings, Wright told msnbc.com, “That’s always something that we’re looking for, but as of this point, we have not been able to establish that that had anything to do with the attack.”

Friend and co-worker Samantha Garrett said she was surprised to hear the news because she had not witnessed any aggression towards the two in the past.

“I’ve been trying to think of anyone that I know that would actually want to harm them for any reason, especially for them being a couple, and not one person has come to mind,” she said.

Wright speculates this was not a random attack but currently has no leads to possible suspects.

Friends have gathered at Ingleside High School and told kristv.com that the two had been together for five months prior to the incident.

The shootings have shocked the local area, with the last homicide there reported over two years ago.
