Drummond Jentzen, 45, was fatally shot in the fall of 2017 at a Phoenix home where he had been allowed to be. A woman who lived there called 911, saying she heard a gunshot and found Jentzen injured outside and tried to perform CPR. Phoenix police later reviewed surveillance video that conflicted with her initial account and, after further questioning, developed a different sequence of events.

Days after the shooting, detectives arrested 37-year-old Shaun Williams, the woman’s fiancé, on suspicion of second-degree murder. The investigation pointed to a more complex, possibly personal motive rather than a random act.

Did anyone know Jentzen or have information about his movements in Phoenix that fall?
