A cast of regulars was drinking one Saturday night in February 1983 at a dive called My Wife’s Place. La Grande was — still is — a place where everybody knows everybody, nobody is ever too far from a cousin or a classmate, so people at the bar that night had history. Romances, breakups, feuds. Two of them flirted and then squabbled. Around 3 a.m., after a quick stop at another nearby bar, the patrons made their way home.
