Thank You for all the narrative. Even though I have listened to interview it does help.
Just to add to certain points above - Will not comment on DNA recovered from the scene - It was stated that some people were being tested for DNA, which is interesting to note. Also that DNA from crime scene/evidence is still being tested and results are not back yet. So he pretty much answered the question even though at the end he stated no comment.
Another points to add - some phone calls are being monitored...
- social media are being monitored but not 24/7
I am actually quite glad that they are not zooming yet on one theory only without supporting evidence and that everything is still on the table. They are also checking on all theories no matter how far fetched they might sound to some. Once some evidence will surface they will take correct direction.
Edit: Adding video of interview -
