A defense @-@ appointed expert witness in the field of biomechanics testified on March 5 that Nosek could not turn 180 degrees during the fall and that should he be falling forward , he could not have sustained an injury to the back of his head . He further said that if Nosek fell over the first row of the fans , he must have been not only pushed , but must have jumped himself . The State Attorney immediately attacked this testimony , claiming that the expert witness omitted the conditions at the place and time , as well as some of the eyewitness testimonies , according to which Nosek fell onto his back from the beginning and did not turn during the fall . The presiding judge agreed with the State Attorney on some of his points .
