Massachusetts police had probable cause to charge Amy Bishop after she shot her brother to death in 1986, the local DA says. Missing police files from the case finally turned up, and the DA says cops could have arrested Bishop on charges of assault with a dangerous weapon and lesser offenses. It's moot now, however: the statute of limitations has run out, reports the Boston Herald.
The development leaves unanswered for now the big questions in the case: Why did authorities let Bishop go free, and how did the files from the case manage to disappear for 20 years or so? The DA's statement notes that Bishop's mother had at least minor political ties. She "was one of 240 elected Town Meeting members. She represented Precinct 3 from 1980 to 1993." Amy Bishop remains jailed after the shooting of fellow professors in Huntsville, Alabama.
