Annan faced intense questioning by the police regarding the incident, during which she confessed to shooting Kalsted.
According to Annan, the two had engaged in a heated argument that escalated as they both reached for a gun.
She managed to seize the revolver first.
Concerned that the sound of the gunshot might have alerted her neighbors, she played a jazz record to mask the noise.
Eventually, she contacted her husband, who then notified the police upon returning home.
During the interrogation, detectives overlooked asking Annan the crucial question of why she shot Kalsted.
That oversight proved problematic for the government case, with prosecutors unable to get their story straight on the motive.
The case resulted in an acquittal.
Annan’s husband stayed by her side during her trial, before breaking up afterwards.
Her next marriage lasted just three months.
The 2002 film won the Academy Award for Best Picture.
