O.C. Smith and his attorneys left the courtroom feeling pretty good about how day went. It was a day of prosecution witnesses. Explosives expert Lloyd Erwin, who works for the ATF, testified about the bomb strapped around Smith's neck. He said it was a series of three cans inside each other with 5,000 B.B. Gun pellets wires, a 9-volt battery and steel wool used as the igniter. Irwin told the jury the barbed wire on the bomb and on the former medical examiner did not come from Smith's farm and the paraffin wax used on the bomb did not come from the medical examiner's office. At the top of the bomb were religious notations JMJ for Jesus, Mary and Joseph and Tamper Proof. Alex Garraro another ATF explosives expert testified the bomb was motion sensitive and could have exploded if Smith moved. The last witness to testify was Dr. William Oliver, an expert on whether a wound matches the object that was supposed to have caused it. Oliver, took each photo of Smith's body and showed jurors where the wounds did not match the story Smith told, especially involving the lye he said was thrown on him. Oliver testified Smith should have had more severe burns especially to his eyes. Defense attorneys pointed out that Oliver only looked at photos and never examined Smith. Jerry Easter, Smith's attorney said, "We were just trying to point out he had limited information upon which he was trying to make an opinion. I hope the jury understood that." The trial will continue Wednesday in federal court.
