Victim's sister says police have 'very viable' lead in 50-year-old unsolved slaying of Michigan attorney

Theory Briefing

• Three competing theories surround Kensler's death: a bitter dispute with a prominent attorney, an angry client, or a third unknown motive.
• Nearly five decades later, the victim's sister says police now have a 'very viable' lead — suggesting the case may not be cold for long.
• The long gap between the killing and any breakthrough raises the question of whether key evidence or witnesses have survived the decades.
• Rival explanations pointing to different suspects mean investigators must weigh which grievance was lethal enough to cross into murder.
