It was a busy week one of the trial against the Texas teen accused of murdering another teen at a track meet last year. The prosecution called a total of 21 witnesses to the stand, resting their case against Karmelo Anthony Saturday afternoon. Jurors heard from coaches and other students who were in the tent at the time of the stabbing of 17-year-old Austin Metcalf. The defense ended the Saturday court session by calling its first witness to the stand.
