Detectives looking into the shooting deaths of a lesbian couple in the Utah mountains last week have called in federal and state investigators to aid in the investigation.

Grand County Sheriff Steven White told Fox 13 that he has asked the FBI and the State Bureau of Investigation to provide extra resources as his department combs through evidence related to the murders of Kylen Schulte, 24, and Crystal Turner, 38.

Schulte and Turner, who is also known as Crystal Beck, were last seen with friends at a tavern in Moab on August 14, as CrimeOnline previously reported. Their bodies were found on August 18 at their campsite in the La Sal Mountains southeast of Moab.

“Just know that everything is being done that we can possibly do, that is why we have asked for the additional resources,” White told Fox 13. “We want to make sure we do it thorough, we do it complete and we do it right.”

White said extra patrols have been established, especially in the mountain areas, although investigators have said they believe the killings were an “isolated incident.” He said detectives can’t share many details in order to preserve the “integrity of the case.”

“Right now, we are not taking anything off the table. We are investigating this at every possible avenue for every possible thing,” he said.
