"We don't know what happened. We obviously have had ideas. We believe she was murdered, absolutely," said Breaux. "I'm going to be honest, she confided in me about how worried she was for her safety when we went to Marfa, Texas almost a month ago. We were sitting down at dinner and she lost it. We walked back to our hotel room and she confided in me that night in things. I looked at her [and thought], 'She's petrified. This girl is scared for her life.'"

When asked who Alexis was worried about, they remained silent. The friends did not want to disclose who Alexis feared in her life because they did not want to jeopardize the homicide investigation.
