A Bucks County judge today sentenced Robert Diamond, a mentally ill Bristol man, to death for the Aug. 1 shootings outside the Simon & Schuster warehouse in Bristol.

Judge Rea B. Boylan pronounced the sentence after hearing four days of evidence against Diamond, who had pleaded guilty Monday to two counts of first-degree murder.

Diamond, 33, showed no emotion as Boylan condemned him to death. His family members left the courthouse without commenting.

Diamond admitted shooting to death Angel Guadalupe, 46, of Falls Township; and Reginald Woodson, 52, of Willingboro, N.J., outside the warehouse where he once worked. Prosecutors contended that Diamond acted in part out of racially tinged malice toward minority workers at the warehouse, who he believed had conspired to get him into trouble on the job.

District Attorney Michelle Henry, who prosecuted the case herself, called the death sentence "the only just verdict."

But defense attorney Barnaby Wittels, who had argued that Diamond's longtime mental illness was behind the shootings, angrily denounced the judge afterward, calling it a "travesty of justice" and "against the law."
