On the afternoon of August 22, 2015, 26-year-old Kyle Jackson was standing beside a road in Nampa, Idaho, wearing red, waving a red bandana, yelling and making gestures at passing drivers; some witnesses said he may have been waving a knife. Police were called and an officer warned Jackson that his behavior was antagonizing and might provoke someone, but no arrest was made because no one would go on record as a victim of disturbing the peace.

A few hours later a black SUV stopped and a confrontation occurred. During the argument Jackson allegedly slashed at 20-year-old Alberto Chavez with a knife; as Jackson turned to walk away Chavez, who was a passenger, produced a .38 revolver and shot him once in the back of the head. Jackson was taken to a hospital and died from his injuries.

Detectives traced suspects to a Nampa residence, followed a Chevrolet Trailblazer the next day and attempted a traffic stop; the driver fled at high speed through two counties, peaking at about 90 miles per hour, before officers used a maneuver to stop the vehicle. Three men were arrested: Alberto Chavez was later charged with destruction of evidence and pleaded guilty to second-degree murder; Luis Castillo-Rodriguez, 21, was charged with harboring a felon; and 36-year-old Robert Johnson was charged with felony eluding.

Are there witnesses who saw Jackson on that stretch of road or the SUV before the shooting who haven’t spoken to investigators?
