At a brief hearing early Tuesday afternoon at the Stamford courthouse, Darnell Crosland, defense attorney for murder defendant Deshawn Hayes, 25, of Givens Avenue, said he wanted to put the state to its evidence and call a hearing in probable cause. When the three got into a black Jeep parked on Delaware Avenue, the witnesses got into another car and followed, while calling 911 and giving police a description of the vehicle the three were fleeing in. After witnesses told police it was Telemin-Valero who fired the shots, he was charged with murder the day after the mother of five children was gunned down in the park with a bullet to her abdomen. Many defense attorneys at the courthouse shy away from calling such hearings because once the hearing happens the evidence in the case against a particular defendant is preserved forever, even if at the time of the trial the witnesses who testified at the hearing are dead or cannot be found.
