BOSTON, Nov. 22 (UPI) -- Police in Boston are reviewing their investigation of a 1991 bombing that killed one officer and wounded another, authorities say.
The convicted bomber, Alfred W. Trenkler, is awaiting word from federal prosecutors on his recent bid for a new trial, the Boston Herald reported Sunday.
A book about the case has raised questions about evidence offered at the trial. Some jurors from the trial who've read the book say they now have doubts about his guilt, the Herald said.
Trenkler was convicted with another man, Thomas Shay, of planting the bomb in an attempt to kill Shay's father for insurance money. The bomb, discovered under a car, killed patrolman Jeremiah Hurley as he was attempting to dismantle it.
Retired Maine attorney Morrison Bonpasse has campaigned to have Trenkler's case retried. His book, "Perfectly Innocent," claims there is new evidence and alleges prosecutorial misconduct and flaws in the investigation, the Herald said.
