Shawn Nathan Fisher is charged with first-degree murder in connection with a road rage crime spree in February where he is accused of shooting at one driver and killing another.
An Ada County grand jury indicted Fisher on the murder charge Tuesday, finding evidence that he used a .38 caliber handgun to shoot and kill Matthew Mohler-Kerns on Feb. 19. The 28-year-old Mohler-Kerns died from a shot to the head as he sat in his car on Franklin Road.
Boise Police say Fisher shot into another car during a different incident minutes before in the Vista Avenue neighborhood over a parking dispute.
Police have the .38-caliber revolver used in that shooting. Police also found five rounds of .38-caliber ammunition and an empty ammo box for .38 rounds in Fisher's Boise Bench apartment, according to the search warrant documents obtained by the Idaho Statesman.
What court documents do not provide are any connection or motive between Fisher's actions that evening and Mohler-Kerns' death. The indictment does accuse Fisher of shooting and killing Mohler-Kerns with premeditation but does not say why.
Fisher, who is being held in the Ada County Jail on a $500,000 bond, is also charged with felony counts aggravated battery, aggravated assault, use of a weapon in the commission of crime and a misdemeanor count of kicking a police dog.
Police say Fisher started his crime spree in the early evening of Feb. 19 when rammed into a car and fired a bullet into its driver's side door following a parking dispute at a Vista-area apartment complex. Hours later, Fisher got into a confrontation with police. It ended with a police dog pulling him from behind a home in South Boise.
In between, Mohler-Kerns was found dead not far from where the driver of the car from the Vista apartment worked and from where the driver called police.
Police haven't said if they suspect that Fisher followed the driver of the car from Vista to the Franklin Road area, where Mohler-Kerns was shot.
The court documents do support police reports that Fisher was intoxicated at the time of his arrest.
Police say they found Spice and bath salts (synthetic marijuana and amphetamine stimulants) in his home the next day. Fisher told police he was taking lithium - a drug used to treat manic depression and bipolar disorder - with "new age and research drugs, " according to search warrant documents.
Fisher also told police he had been "receiving threats from his Xbox from a secret society."
Fisher is set to be arraigned in front of 4th District Judge Ronald Wilper on Tuesday. If Fisher pleads not guilty to the charges, a jury trial will be set for later this year.
The crime of first-degree murder is punishable by up to life in prison without the possibility of parole.
