Joel Infante was the technician who collected evidence the night Wanda Lopez was killed. He said he found three fingerprints inside the station, but all were of such poor quality as to be worthless. He was unable to get fingerprints from the knife or a pack of cigarettes on the counter. Infante took no samples of the blood spatters on the floor of the station, so there was no way to determine whether the attacker?s blood was present.
