My parents and brother owned and operated a recreational vehicle sales, campground and mobile home park in a rural area of Northern Wisconsin. One of the tenants in the mobile home part was a young, single guy — a loner, kind of odd, but my mother had checked him out and they weren’t afraid of him. One morning he walked up to my mother in our backyard, where she was hanging laundry, and shot her in the head. Then he proceeded to the RV sales office next door. He waited for a customer to leave and then shot my 22-year-old younger brother in the head as well as his 22-year-old coworker and friend. He then waited for my father to return to the office and killed him.
