The Delahunt/Amy Bishop connection.

So the news comes out that the University of Alabama-Huntsville biology professor, charged with murdering 3 colleagues, shot her brother to death, back in 1986, and the District Attorney's office made the decision not to file charges. The District Attorney was William Delahunt, who has been a member of Congress since 1996.

[Braintree Police Chief Paul Frazier] said Bishop was being booked into jail when then-Chief Polio, or someone on his behalf, called and ordered the booking process stopped. Bishop was then released to her mother.

Frazier said the records from the case have been missing since at least 1987. "I don't want to use the word 'cover-up,' but this does not look good," he said.

“I was not on duty at the time of the incident, but I recall how frustrated the members of the department were over the release of Ms. Bishop," Frazier said. "The release of Ms. Bishop did not sit well with the police officers and I can assure you that this would not happen in this day and age.”...

In an interview at his home Saturday, Polio, 87, told the Globe: "There was no cover-up." 

And the next thing you know, Delahunt says he may not run for reelection.
