A 42-year-old Lockwood man pleaded no contest Tuesday to a felony charge for stabbing his mother in the back.
Bobby Nikolas Kouris appeared before District Judge Russell Fagg and entered a conditional admission to the charge of felony assault with a weapon.
A defendant who pleads no contest does not admit guilt but acknowledges that prosecutors have sufficient evidence for a conviction.
Fagg set a sentencing date of April 25. Kouris remains free on bond.
A plea agreement states prosecutors and Kouris' public defender will recommend that he receive a six-year deferred sentence with placement in a Missoula group home or similar facility where he can receive mental health treatment.
Kouris was charged for an incident on Sept. 2 at a Lockwood residence where he lived with his mother. The woman told a deputy that she was sitting at a computer when she felt something hit her back.
The woman turned around and saw her son standing nearby holding a knife. When she asked him what he was doing, he replied he was "hearing voices."
The woman told her son to go to his room, then stepped outside and called for help.
A deputy who arrived said the woman had a large bloodstain on her back. Kouris was arrested inside the residence still holding the knife.
A mental health evaluation after his arrest determined that Kouris was legally competent and could be tried for the assault. Further information about his mental health condition was not disclosed Tuesday.
