DNA evidence is the subject of new testimony in the third David Camm murder trial. Jurors heard yesterday from an Indiana DNA expert who explained where Camm and the convicted killer of his wife and children left their imprints. Defense attorneys are trying to prove the evidence was mishandled by noting it took nearly five years to link DNA to Charles Boney and that Indiana State Police rushed to charge Camm. Camm is charged with the murders of his wife and two children at their Georgetown, Indiana home on September 28th of 2000. Two Previous convictions have been reversed.
