Here is visible trace of WATER, PROBABLY RAIN OR SOMETHING ELSE. WATER PROBABLY RAIN IS VISIBLE ON THE STREET JUST AT THE TOP OF BELOW IMAGE. THAT IS MEANIMG, THAT AFTER EVENT WAS RAIN AND ALL THE MUD ON IMAGES BELOW COULD BE FROM RAIN.
There is very interesting COVER UP for this EVENT from official police in Sarajevo, Bosnia. I try today Monday 10 October
to find which police investigation team was there but without progress. I visit 3 police headquarters but complete silence. Still trying to get more info.
