You need to apply context imo. KR has not taken the stand but her defense are not denying she called her folks and are not contesting that she did so in the early am hours. (Imo because they know it is hardly a point that the jury will struggle with or find relevant to their deliberations).
In contrast, both BA and BH and also JMc have denied and imo certainly lied about making late night and early morning calls. In the case of BA and BH they deny having a conversation at 2.30am or whenever it was, when records show a phone call was made and answered. In the case of JMc and Nicole Albert both deny having two conversations. JMc denies making the calls and Nicole Albert denies answering them even though records show that both those things happenned.

I'm wondering if you see that context matters here. KR hasn't lied.
