( CNN ) -- A 911 call released Wednesday recounts the moments after soccer referee John Bieniewicz was fatally punched in the head by a player during an adult-league soccer match in Michigan . `` The referee is knocked out , '' a female caller frantically told a 911 operator on Sunday . `` He 's not waking up . '' Bieniewicz , 44 , an avid soccer fan and referee who sometimes officiated up to three games a weekend , died Tuesday . In a state where football and basketball reign , Bieniewicz 's passion was soccer , a childhood friend recalled . `` He loved the game of soccer . He loved refereeing ; it was like free time to him , '' Greg Acho , the friend , told CNN . `` He died doing what he loved . '' The woman who called police also described the alleged suspect fleeing the scene as the victim was unconscious on the field . `` It looks like a ... oh God , they 're peeling out , '' she told the operator . `` It 's a Jeep . It 's a black Jeep Wrangler . They 're peeling out of the parking lot right now . '' The suspect left the scene , she said . An ambulance was needed . The operator asked what did they hit him with . `` His fist , yeah , in the middle of the game , '' the woman said . The woman said the referee was not breathing . Others on the field attempted CPR . Bieniewicz was pronounced dead at Detroit Receiving Hospital after what police said was an unprovoked attack . A supervisor at Mott Children 's Hospital in Ann Arbor said he was in critical condition when he arrived the hospital , police said . The Wayne County Medical Examiner 's office will determine the cause of death , police said . Baseel Abdul-Amir Saad , 36 , has been charged with assault with intent to do great bodily harm less than murder . He was being held on $ 500,000 bail , police said . He pleaded not guilty . A hearing was set for July 10 . Bieniewicz is survived by his wife and two sons , 13 and 9 . His friends have established a GoFundMe.com account for his family that had raised nearly $ 60,000 by Wednesday afternoon . Acho said donations will be used to cover medical expenses , funeral costs and to start a college fund for his children . Bieniewicz was an organ donor , Acho said . `` John Bieniewicz was a man who lived life to the fullest , '' friends wrote on a website dedicated to his memory . `` He had a passion for his family , a passion for the kids at Mott Children 's Hospital , and a passion for soccer . '' Saad 's defense lawyer , Brian Berry , expressed his condolences to the family of the referee but told CNN Tuesday that all the facts in the case had not come out and that `` witness accounts may have been miscategorized . '' The website dedicated to the victim added , `` The boys will miss his fatherly guidance and support but they will also miss his financial support , and we are here to help that in a small way . If you were touched by John , or merely share his love of soccer , we ask that in his name you donate to his children 's futures . '' Last year , a 17-year-old soccer player in Utah pleaded guilty to homicide by assault in the death of referee Ricardo Portillo . A judge ordered the teenager , who was not named publicly , to keep a picture of Portillo in his cell for the remainder of his time in juvenile jail . The judge recommended a sentence of three years , said Salt Lake County District Attorney Sim Gill . The teen also was ordered to write weekly letters to Portillo 's family , telling them what steps he is taking to return to normal life .
