"Although no clear motive (behind the attack) has been established, initial indications are this shooting was not a random act. There was no previous confrontation between occupants of either vehicle," Wayne Miller, Port Orange's Assistant Chief of Police was quoted as saying by local daily Daytona Beach News Journal.
Meanwhile, the authorities said on Monday that the incident of shooting will be probed by the agencies as a hate crime.
Condemning the act, the Sikh American Legal Defence and Education Fund (SALDEF) and Sikh Coalition called on the law enforcement officials and requested them to conduct a thorough probe into the incident.
