Superior Court Judge Craig Matheson on Tuesday said that murder suspect Joseph W. Hart will undergo another psychological evaluation to determine his competency to stand trial.
Hart, 28, in 2012 spent almost five months in a state facility where mental health experts worked to restore his competency.
Hart is a schizophrenic with an antisocial personality disorder, and has abused drugs including alcohol, marijuana, methamphetamine, heroin and LSD, a psychologist wrote in a previous evaluation in the Franklin County case.
That psychologist said Hart has "capacity to understand court proceedings and productively participate in his own defense."
But Scott Johnson, Hart's attorney, requested the additional assessment because of concerns about his client.
Hart has pleaded innocent to one count of second-degree murder for the March 2012 death of Rodger A. Lincoln. The charge includes a domestic violence allegation because the men were roommates.
The two men shared a home in the Sundance Mobile Home Park on North Elm Avenue.
Lincoln, 53, died after several stab wounds to his head and torso by a hunting-type knife, an autopsy showed.
