The case was re-opened after a medical examiner ruled Brady's death last August a homicide caused by injuries from the shots fired by Hinckley 34 years ago.
That opened the door for murder charges against Hinckley; but now prosecutors have decided against filing anything new.
NBC quotes prosecutors in the case who said that since a court had already ruled Hinckley legally insane "the government would be precluded now from arguing that Hinckley was sane at the time he shot Mr. Brady."
The Washington Post reports that Hinckley's attorney said in August there were "insurmountable legal barriers" with the case and stated the basic elements of the crime had not changed in the three decades since the shooting.
Brady was shot in the head, causing paralysis in his left leg and arm, memory loss and slurred speech.
The shooting turned Brady and his wife, Sarah, into lifelong gun control advocates. They eventually helped pass legislation requiring background checks for gun purchases.
