A Wyoming man accused of opening fire inside the Hazel Dell Wal-Mart in October was arraigned Wednesday after a mental health evaluation found he is competent to stand trial.

Shaun Michael Sprague, 35, of Sheridan, Wyo., entered not-guilty pleas in Clark County Superior Court to aiming or discharging a firearm, reckless endangerment and third-degree malicious mischief. In addition to the shooting, Sprague is suspected in an unrelated residential fire in Hazel Dell. He entered a not-guilty plea to first-degree arson.

His trial is scheduled to begin Feb. 13.

Sprague was ordered Oct. 12 to undergo a competency evaluation, which found he is able to aid in his defense. Competency in the court system only addresses whether a defendant is able to assist in his defense; it doesn’t address all of a defendant’s potential mental health issues.

Sprague told authorities after the shooting that he took “speed” — a term for amphetamines — a couple days prior and planned to kill himself but changed his mind, according to a probable cause affidavit. He also told jail officials that he suffers from mental health problems, court records show.

Clark County sheriff’s deputies arrested Sprague shortly before 7 a.m. Oct. 4 inside the Wal-Mart at 9000 N.E. Highway 99 after a store manager called 911 to report an active shooter. No one was injured during the shooting.
