Video of a fight that broke out in a holding cell at the Allen County Justice Center between a murder suspect and a witness in the case is shown during the trial of Markelus Carter. Â
Carter is on trial for the 2009 murder of Kenneth Warrington. Â
During the afternoon break on Wednesday, Carter was mistakenly placed in a holding cell with Steven Upham.  The video shows Carter landing the first punch with Upham later putting Carter in a headlock and throwing a few punches followed by Carter biting Upham on the arm.  Corrections officers break the fight up after about two minutes. Â
Thursday morning Carter's lawyer Jon Paul Rion asked for a mistrial based on the fight.  However, Judge Jeffrey Reed said the case would move forward and allowed the video to be shown to the jury.Â
Upham was a block mate of Carter's at Allen Oakwood Correctional Institution.  Upham testified that Carter told him details of the murder.   Â
On cross examination the defense pressed Upham on other ways he could have obtained information on the murder besides a direct conversation with Carter.
Upham then admitted he spent a great deal of time in prison trying to find ways to get released early.  However, he denied being promised any reduction in exchange for testimony in this case.  Â
Three guards were placed in the courtroom during Upham's testimony.  The defense is expected to call other inmates to the stand to refute today's statements. Â
Later in the day, the state continued building its case by calling lead detective Tim Clark to the stand.  Clark's testimony will continue Friday morning. Â
