The Tennessee Criminal Court of Appeals has upheld the murder conviction against a man convicted of killing his mother in law with a hatchet.

In March 2007, police say Robert Fritts repeatedly struck Teresa Busler with a hatchet several times and sprayed her face with white paint.

The case took another bizarre turn in court. Prosecutors introduced evidence showing Fritts was part of a gang of juggalos, or people with the rap group "Insane Clown Possey."

The group wears white-face clown make-up, and its record label features a hatchet wielding man.

Fritts argued it was improper for lawyers to introduce that evidence, but the court decided Monday to uphold his sentence of life without the possibility of parole.
