But Ada County prosecutors said Thursday they are investigating treatment options for 38-year-old George Nickel Jr.

Nickel was charged with one count of unlawful discharge of a firearm into an occupied dwelling, four counts of assault or battery of a law enforcement officer, and one count of using a weapon in the commission of a felony. The potential deal would drop the rest of the charges if he pleads guilty to shooting the gun into the apartments.

One of 100 Idaho Army Reservists with the 321st Engineer Battalion who spent a year in Iraq hunting and disarming roadside bombs, Nickel has been in the Ada County Jail since his arrest.

His criminal case was put on hold after a judge ordered a mental health evaluation in August to see if Nickel was mentally competent to understand legal proceedings against him and actively participate in his defense.
