I also have a 2011 co-worker murder. The guy went home and shot his wife in the head. They lived in Independence. He was manufacturing supervisor on a program I was managing. I was working in his office after he left and didn't notice he left his badge and blackberry on his desk. I talked to him 90 minutes before he did it. Apperantly they'd previously has problems, reconciled, and she had just decided to leave again. He got home, went straight to get his shotgun, shot her in the head while the kids were in the back yard swimming, then called his brother to come get his 4 kids because he'd just killed their mom.
