A Garfield man is fit to stand trial on murder and robbery charges in connection with the deaths of his mother and grandmother, according to Monday’s ruling by Circuit Judge Robin Green.

Nicholas Johansen, 21, is charged with two counts of capital murder and two counts of aggravated robbery.

He is accused of killing his mother, Christina Bishop, and his grandmother, Louise Bishop, 81.

Johansen had been ordered to undergo a mental evaluation at the Arkansas State Hospital in Little Rock.

Green found that Johansen was fit to stand trial as result of the evaluation at the State Hospital.

Documents related to the evaluation have been sealed by the court.

Michael Shane Winters, Johansen’s co-defendant, was found guilty in November 2011 on the same charges Johansen faces. He was sentenced to life in prison and is incarcerated at the Cummins Unit of the Arkansas Department of Corrections.

Johansen is being held without bond in the Benton County Jail.

Prosecutors are seeking the death penalty.

If convicted of capital murder, Nicholas Johansen faces life imprisonment or a death sentence. He could be sentenced from 10 to 40 or life imprisonment on each of the aggravated robbery charges.

Johansen previously pleaded not guilty to each of the charges.

Police believe the two women were killed June 18, 2009, at their Bentonville home on Southeast J Street. The Bishops were reported missing June 21, 2009. They were last seen at Sam’s Club in Bentonville, according to court documents.

Their bodies were found Feb. 16, 2010, in a grave at 15226 Sugar Creek Road, between Garfield and Avoca, according court documents.
