On the evening of May 27, 2024, Centerville, South Dakota lost three men to gunfire: 26-year-old Paul Frankus, his 21-year-old brother Zachary Frankus, and 35-year-old Timothy Richmond. A 911 call from Zachary at 9:44 p.m. reported Paul had been shot by a neighbor; the call went silent after Zachary was himself shot. Officers arriving at the home found all three victims had died of gunshot wounds.

Police encountered 64-year-old Jay Edward Ostrem, a former Centerville mayor, leaving the scene. He was arrested carrying an AR-style rifle and a handgun and was described as smelling of alcohol. Court documents allege his wife told him Paul had sexually assaulted her days earlier and that Ostrem reacted by leaving the house in a rage. Ostrem has been charged with multiple felonies, including three counts of first-degree murder, and has pleaded not guilty, not guilty by reason of insanity, and not guilty but mentally ill; he is held on a $1 million cash-only bond.

Did anyone in or around Centerville have contact with the victims or Ostrem in the days before May 27?
