Psychologist: Bucks man 'psychotic' when he confessed murder

A schizophrenic Bucks County man was mentally incapable of waiving his Miranda rights when he confessed to the Aug. 1 slayings of two workers at a Bristol warehouse, a psychologist testified this afternoon in Bucks County Court.

Robert Diamond was too psychotic that day to knowingly give up his rights to remain silent and to have a lawyer present before speaking to a Bristol Borough detective, neuropsychologist Jonathan Mack said at a pretrial hearing.

"Mr. Diamond was unable to waive his rights," Mack said. "He was absolutely in a very psychotic state at the time."

Diamond, 33, faces the death penalty if convicted of first-degree murder in the shooting deaths of Reginald Woodson and Angel Guadalupe outside the Simon & Schuster warehouse on Radcliffe Street. Guadalupe, 46, of Falls Township, was backing his vehicle out of the lot after his shift when Diamond allegedly shot him to death.

Woodson, 52, had left the warehouse to intervene, and was fleeing back inside when Diamond shot him in the back, police have said.

Diamond, of Bristol, had been terminated several weeks earlier from Simon & Schuster. Prosecutors allege that he was angry over what he perceived as preferential treatment given minority workers after he had complained about some of them. Diamond's attorney, Barnaby Wittels, has filed notice that he may pursue an insanity defense.

At today's hearing, Wittels is trying to suppress a confession Diamond gave shortly after being arrested at the scene.

When Mack's testimony resumes, it could provide the first glimpse into Diamond's mental state.

According to court records, Diamond was diagnosed with paranoid schizophrenia more than 10 years ago. Mack testified that his examinations of Diamond showed that multiple head injuries and a history of substance abuse had also left him impulsive and forgetful.

District Attorney Michelle Henry, who is prosecuting the case herself, is seeking the death penalty because the shootings involved multiple victims and because they occurred in a public setting that put others at risk as well.

This afternoon's court session is expected to include the playing of a recording Diamond made of his thoughts while en route to the scene of the shootings.
