These copies are from the actual ledger of the Saffell Saloon and lists the number of drinks each customer had. Notice on the 12th, Montie Slaughter had more drinks than Ed Beeler.
Jack Becker's Note:
Gus Becker said that after Beeler killed Slaughter, he walked over to Becker's store where the Sheriff's Office had jail cells and an office upstairs. Not long after, the Slaughter's came looking for him. Gus told them that Beeler was upstairs and told them "I gave him my shotgun to defend himself."
