The Big Blow

This features one of the few occasions when James Doohan has his right hand (and its missing finger) visible on screen, when he is cutting himself some roast beef. He lost his middle finger to friendly fire on D-Day on Juno Beach at Normandy when he was shot four times in his right leg and once in his hand by an overzealous sentry with a Bren gun.

Around the :44:15 mark, the killer opens a case with a silenced automatic pistol. However, around the 46:20 minute mark, Magnum relieves the killer of her weapon which is a revolver.
