This is Costak's first official logo (April 23,2006)
Petri committed more murders during his short life. "Costak" is however a film that brings characters from today into the times and tribulations of Petri and is not his full life story. Changes were made for the film and the real life provides only an inspiration. It is a legend that after each murder as he ran away he casted his slippers to run faster. Police in many cases connected the murders to Petri solely on the base of slippers found near a crime site.
