WASHINGTON (AP) — This week’s death of former White House press secretary James Brady, who survived a gunshot wound to the head in a 1981 assassination attempt on President Ronald Reagan, has been ruled a homicide, District of Columbia police said Friday.

Federal prosecutors said only that they are reviewing the ruling. But a law professor and an attorney for John Hinckley Jr., who was found not guilty by reason of insanity in the shooting, said bringing new charges against the 59-year-old in Brady’s death seemed unlikely.
