Washington -- A Pennsylvania woman convicted in a bizarre bank robbery that involved a pizza deliveryman with a bomb attached to his neck lost her Supreme Court appeal on Monday.
The justices, without comment, turned aside claims from Marjorie Diehl-Armstrong that she was innocent and mentally incompetent to stand trial.
Diehl-Armstrong, 63, was convicted of conspiracy and other charges related to the death of pizza deliveryman Brian Wells in 2003.
Authorities said Wells walked into a PNC Bank branch in Erie, Pennsylvania, on August 28, 2003, with a pipe bomb locked around his neck, and gave the teller a note demanding money. The robbery netted about $8,700.
Wells was killed when the bomb detonated as he sat in a parking lot after being stopped by police.
The case drew national attention and was the subject of an intense investigation.
