This is wrong.
The investigation was never paused. Last week the prosecutor did claim he would pause the investigation, but that was a misleading claim from the very beginning - with the sole purpose to calm the public. Although that didn't work out (the demonstrations happened nevertheless), it achieved some strange success: The media keep repeating and repeating that, despite having no evidence that anything was ever paused.
The only "pause" that exists is that the investigation is currently waiting for an assessment ("Gutachten"). However, that is normal part of the investigation and would have happened anyway. So this is "waiting" (passive), not "pausing" (active). The prosecutor didn't do anything here to pause the investigation.
