There were no live witnesses to the crimes, no videos of the crime, and no fingerprints or DNA evidence. In a fourth robbery, the owner of a small grocery store was critically wounded but was alive and conscious enough to give an excellent description of the perpetrator. He then clearly identified the man from a photo array. Because of the critical condition of the victim, and immediate preliminary hearing was scheduled after the suspect was arrested and charged. The judge , the defense lawyer, and the prosecutor (with other court attendants) conducted the preliminary hearing in the hospital rooom of the victim in the presence of the defendant. Pain medication was withheld for a day from the victim at his request. The victim clearly identified the defendant as the robber was responded to cross-examination by the defense lawyer. An early trial date was set, but the victim died before the trial.

2. The series of robberies and murders stopped with the arrest of the defendant. Can this be used as evidence?
3. "Ballistic fingerprints" were available, but no murder weapons were found that could be matched to the prints. Can the defendant be convicted of the other robberies and murders based on the available evidence?
