INDIANAPOLIS (AP): Authorities have dropped a preliminary murder charge against a man arrested in a deadly shooting near the Indianapolis Motor Speedway.
 
       Marion County prosecutor's office spokesman A.J. Deer said Wednesday there were problems with witnesses' identification of 19-year-old Avory Johnson.
 
       The Indianapolis man had been jailed since he was arrested soon after the shooting death of 25-year-old Max Levine of Kokomo in a parking lot near the track about 2 a.m. Saturday.
 
       A Marion County Jail spokesman says Johnson was released Tuesday afternoon.
 
       Police say an argument preceded the shooting. Levine's mother says her son was camping in the lot with a group of friends before Sunday's Indianapolis 500.
 
       Deer says prosecutors are continuing to work with investigators and charges could be refiled later.
