Trial en Bridge bomb suspect wants past threat excluded from trial evidence <p>One of five suspects charged with plotting to bomb a highway&nbsp;bridge in Ohio wants to exclude&nbsp;trial evidence that he threatened to&nbsp;bomb his seventh-grade principal. Attorney Anthony Vegh told a&nbsp;federal judge&nbsp;in Akron that information&nbsp;about the threat&nbsp;by Douglas&nbsp;Wright of Indianapolis when he was 12 years old would prejudice&nbsp;the jury. The&nbsp;judge said&nbsp;Thursday&nbsp;he will take up the&nbsp;issue next month. All five men have pleaded not guilty. They allegedly tried to detonate what turned out to be a dud bomb provided&nbsp;by an informant. Thu, 21 Jun 2012 21:06:36 +0000 Associated Press 17614 at
