A woman charged with slashing the corpse of her boyfriend's ex-girlfriend has been found competent to stand trial.

Special Judge David Youll ruled Shaynna Sims competent after reviewing her psychiatric evaluation. Sims, who did not appear in court, is jailed without bond and has a preliminary hearing scheduled for Sept. 11. She has pleaded not guilty.

Sims was arrested at the dead woman's apartment after attending a viewing April 30. Police say Sims stole the woman's shoes and was carrying a knife with the woman's hair attached to it.

Witnesses told officers that they saw Sims reach into the casket during the viewing. The dead woman's face was slashed, her makeup was smeared and her hair was on the floor.
