Contact in DM Phone that Night - Brittany Fernande

Any ideas of possible connection between the two? Possible she was entering Fernandez as the last name, Z was left off - it happens. There is a rumor that Brittany possibly dated Bryan Kohberger. Also, that Brittany was a former student of University of Idaho. And, there was the hit n run incident that night that involved the Fernandez'. Any ideas of how Dylan would be connected and why the contact was made in DM's phone that exact night, which is weird in itself. Anyone? Thanks in advance.
