A Kootenai Medical Center worker told police that someone fired a bullet at her as she was leaving the hospital's parking garage last week. Kimberly Shaul reported that she thought a tire had gone flat when she heard a loud noise as she was driving down the ramp from the second floor about 4 p.m. Friday. She continued home when she discovered none of the tires were flat. On Saturday morning, she found a bullet hole in the tailgate of her minivan. The bullet also went through the plastic molding on the driver side wall and came to rest on the floor behind the driver's seat. Shaul reported that she didn't see anyone in the garage as she was exiting.
