Yes, and i stated that before.
IMO we should not misinterprete HCW's statements acording to put a line under the investigations. IMO they investigate since 2017/2018 according the known convicted (!) suspect. No need to hurry, no need to fight for an arrest warrant. C.B.'s lawyer just tries to push a little bit pressure into, because his hands are tied, as long as C.B. hasn't been charged or even interrogated by L.E.. For so long he is NOT able to take a look into the files. Not even one sheet!!!!
So HCW can also be understood to mean, L.E. should be soon to hand over the finished investigation to the prosecuters, so they are able to charge him by appealing a german penalty-court, or not. That already starts with an interrogation to finish the investigation. At this point, they have to let the lawyers take a look into the files, to assure an correct defence.
In germany the L.E. investigates a suspect in 1. step, then they hand over all info to the prosecuters (2. Step - HCW, but they can and do work together in some cases), and in the 3. Step the prosecuters check the files and decide, wether they call a court by charging the suspect for a trial.
In Step 4, the judges are in charge for the trial and take over.
The problem in this case is, we have a worldwide known suspect. Even if he get's a trial in the next months, lawyers will argument, he never had a chance for a fair trial, due to public sentencing. Even if he may be guilty at the end. Like the boys in the Bulger case in U.K.. A good prosecuter knows, when it's time to tie the knot.
