Yes, it is significant in the fact that we know K & M were alive at 2:52 am.
The reason there hasn't been more discussion on it is because it was discussed to great depth in earlier threads. Other than the time line, the information really has no value for the following reasons:
- @Zella : "The sister actually stated in interviews that this was a normal habit of K's, to call people in the early hours of the morning repeatedly about mundane things until they answered."
- The recipient of the calls, K's ex, "isn't believed to have been involved" per the City of Moscow homicide investigation update (see below)
- They weren't urgent calls for help due to the fact it took 30 minutes to make a total of six calls. M also made 3 (I believe) attempts to call K's ex in that same time frame. If it was THAT urgent, the calls would have been over a much shorter time frame IMHO.
