( CNN ) -- The man suspected of a series of sex attacks that left an Oklahoma city on edge this summer has died , authorities said , two weeks after crashing his car as he fled the scene of one of the alleged assaults . Desmond Campbell , 30 , was presented with charges related to seven sex crimes last week , even though he was in a hospital bed -- unresponsive and in critical condition from the wreck , Tulsa Police Chief Chuck Jordan said . The state medical examiner 's office confirmed Campbell 's death to CNN Tuesday . `` We were prepared to file 23 felony crimes against him , including rape , robbery and first degree burglary , '' Assistant District Attorney for Tulsa County Steve Kunzweiler said . There were eight linked cases of sexual assault in Tulsa in June , according to police . They were initially linked through specific actions and statements the suspect made during the attacks . The victims were between 56-78 years old , except for one , who was 29 . Campbell was identified as a suspect after an analysis of a `` tremendous amount of absolutely miraculous evidence collection and crime scene investigation , '' Jordan said . The speeding car he was traveling in struck a light pole on an interstate early on the morning of June 29 , about 10 minutes after one of his alleged sexual assaults , Jordan said earlier this month . Campbell , who was not wearing a seat belt , suffered severe head injuries . A complete autopsy , including toxicology tests , will be performed . Results wo n't be available for at least six to nine weeks , the state medical examiner 's office told CNN . `` The death of Mr. Campbell is not going to provide any justice to these victims in a criminal court of law . The justice he will face will come from a higher authority , '' Kunzweiler said . Campbell was released from prison in late April after convictions in Oklahoma City for attempted robbery , attempted kidnapping and robbery , and robbery with a dangerous weapon , Jordan said . He was imprisoned in 2007 .
