It looks to me as if there could be two different persons - one who B called after the murder and another who made the three threatening phone calls.
LE are now saying that they were prank calls to EM's colleague and not related to this case BUT they have not cleared who the person was who B called after the murder hence the confusion.
Then the latest article states: ".....it
does not appear that there was a person who assisted the accused in the cold-blooded murder of his wife. "
"Police note that neither the examination of the scene of Caroline's murder, nor the analysis of telephone calls reveal the involvement of another person in the murder of the 20-year-old girl. of the Attica Security that investigated the case, it was noted that there had been lifting of confidentiality of communications and relatives of the murderer without anything worth mentioning "
But it also states that: "
In the coming days, data on telephone communications, camera footage, banking data are expected to be presented, while
relatives and friends of the couple will be called for deposits."

My takeaway from that is that they have not checked out family and friends yet as it says "it does not appear" that another person assisted in this case.
Why would they have claimed that B phoned someone after the murder if he didn't?
