Mary Kristine Chapa, 18, who was shot in the head on Saturday along with her girlfriend Mollie Judith Olgin, 19, who was killed, is making an “amazing” recovery, her brother told NBCLatino.com.

“Krissy’s health — considering what happened to her — she’s doing amazing,” says Hilario Chapa, 32. “She’s making a strong recovery. The doctors are amazed.”

A couple visiting Andrews Park in Portland, Texas on Saturday saw the bodies of two teens in a grassy area. In a statement, Portland police chief Randy Wright said that while family and friends have confirmed the two teens were in a same-sex relationship, there is no evidence as of yet to indicate the attacks were a hate crime. The Texas Rangers have joined the investigation.

Hilario, a tech sergeant in the Air Force reserve, who served with the 82nd airborne division, says his sister took sign language in high school and has been able to communicate in that way. He says she has made physical progress on her right side but they are still waiting for a response from the left side of her body.

“The doctors say it’s too early, no one is using the word paralyzed,” he says. “They say we should be so happy with her progress after 3 or 4 days. She’s very strong. She survived a very tough ordeal but her recovery is coming in strides and impressing everybody.”
