Jan Metzig, 71, and her husband David, 72, were found dead in their Wolf River, Wisconsin home on the morning of March 18, 2023. The couple, third-generation owners of the Union Star Cheese Factory, were discovered in their bedroom with bags over their heads and apparent gunshot wounds; an AR-style rifle with a loaded magazine was found on the kitchen table and a large amount of blood was reported at the scene.

Suspicion focused on their son Erik Metzig after a 911 hang-up prompted a welfare check. Family members told deputies Erik lived with his parents but his car was missing. Investigators found a journal in Erik’s bedroom containing entries about eliminating his parents and a line asking whether pleading self-defense was justified. Erik was located about 25 miles away and detained; a search of his vehicle reportedly revealed what appeared to be blood smears, and a 9mm handgun was later found in a garage trash bag.

What additional details might help explain the motive or timeline in the hours before the killings?
