A North Texas man charged with carving a pentagram into his 6-year-old son's back has been declared incompetent for trial.
Prosecutors in Tarrant County on Thursday announced Brent Troy Bartel of Richland Hills has been committed to a state mental health facility for at least a year.
Authorities say Bartel in December 2012 called 911, made religious comments and said he etched a pentagram on his son. Investigators believe the father used a box cutter to wound the boy.
Bartel was arrested and charged with aggravated assault with a deadly weapon.
The district attorney's office says doctors last year told a judge that Bartel was diagnosed as paranoid schizophrenic.
Dr. Timothy Nyberg, in an evaluation in January, indicated Bartel has a pattern of making bizarre religious assertions.
