Seeking clarity on Kaylee’s (ex) boyfriend

Caveat: in posting this I am not intending to cast suspicion on this individual, but I want to be clear about what we currently know. Please let me know if I have anything wrong.

• Kaylee was in the process of moving to Texas
• Kaylee broke up with her long-term BF about two weeks before the murders
• Kaylee called her ex 10 times immediately prior to the murders
• Her ex was in Moscow the night of the murders
• Her ex indicated that he missed the calls because he was sleeping.
• Her family does not suspect him, but he has not been publicly cleared by LE at this point.

Is all of that information correct?
