Marc Austwick, 63, and his brother John Austwick, 60, were found dead outside a house fire in Highland Park, Illinois, in the early morning hours of June 5, 2024. Firefighters arrived at the Park Avenue West home around 3:50 a.m. and discovered the structure engulfed in flames and the two brothers lying outside. Autopsies confirmed both died of multiple gunshot wounds: Marc was shot nine times and John four times. The house belonged to their 84-year-old mother, Phyllis Austwick, who had died five days earlier on May 31.

Investigators focused on the brothers’ younger sibling, 54-year-old Jeffrey Austwick, who had been living at the home. Authorities say Marc and John had gone there to discuss the property with Jeffrey; police allege Jeffrey shot both men, set the house on fire, and fled. A nationwide warrant was issued and Jeffrey was arrested in St. Louis on June 7, 2024, reportedly armed with a handgun. He was charged with two counts of first-degree murder and held without pretrial release.

Does anyone have information about the family, the property, or events around the house in early June 2024 that could shed light on what happened?
