A court on Guam on Thursday said it will allow a psychologist to re-examine the man charged with killing three Japanese tourists and wounding 11 other people in a vehicular and knife rampage in February.

Judge Anita Sukola, who is handling the murder case against 21-year-old Chad De Soto, granted the defense motion for an expert witness and ordered a second psychological evaluation of the suspect.

De Soto, a local high school graduate, claims he suffers from a mental disorder. He has pleaded not guilty to charges of multiple aggravated murder and attempted aggravated murder.

Following a court order, an initial evaluation was conducted immediately after De Soto pleaded not guilty, although the results have been withheld.

Sukola also granted a motion for the defense, requesting the transcript of the grand jury proceedings that led to De Soto's indictment.

De Soto stands accused of running down six people with his car and stabbing eight people after getting out of the vehicle on the night of Feb. 12 in Guam's main tourist area of Tumon.

The court has set the next trial session for Oct. 2.
