A man who prosecutors say targeted blacks in a shooting spree that killed three people earlier this year is scheduled for a November 29 arraignment for assaulting a Tulsa County jail detention officer.
Jake England faces charges of elbowing and cursing the officer as he was being taken to his cell from a jail recreation yard on November 1.
A Tulsa County judge postponed England's arraignment on Wednesday.
England and 33-year-old Alvin Watts are both awaiting arraignment on November 26 for the shooting deaths of William Allen, Bobby Clark and Dannaer Fields on April 6. Two other people were shot but survived. All five victims were black.
Prosecutors say the two targeted blacks because the father of England -- who is a Cherokee Indian -- was killed by a black man in 2010.
