A convicted murderer will get a new trial because jurors were not allowed to consider whether he was driven to his homicidal rage by the suspicion his daughter had been molested.

Maurice Lee was convicted of second-degree murder in the July 24, 2002 stabbing death of Melvin Hairston. But a three-judge panel of the D.C. Court of Appeals has tossed Lee’s conviction because, the judges said, the jurors were given the wrong instructions.
