Kimberly A. Coyne, 54, and her 24-year-old daughter Blair Coyne were found shot to death in their rural Saint Joseph, Illinois, home on March 29, 2020. Both women’s deaths prompted an intensive local investigation that identified 30-year-old Jonathon Perry, who was living with them, as the primary suspect. Perry was arrested after his mother called 911 reporting alarming comments he made after the shooting and was charged with two counts of first-degree murder.

Court testimony described Perry as unemployed with a history of substance abuse and mental health problems, and noted prior convictions including DUI and burglary. The killings devastated the family: Kimberly’s father David Cook, her son Justin Awalt and his children, and Blair’s father and uncle were left to cope with the loss.

The case raises questions about what happened in the hours before the shooting and whether warning signs were missed or help could have been sought. Anyone with information about Kimberly or Blair, or who saw or heard anything in Saint Joseph around March 29, 2020, is asked to come forward.
