According to the Phoenix Police account, a trooper was patrolling when he discovered Johnson's vehicle parked at the triangle piece of land between the freeway and on/off ramp, near Loop 101 and Tatum Boulevard. The trooper approached the vehicle and found Johnson asleep at the drivers seat, with cans of beer and a gun in the car, after removing the gun the trooper returned to his motor unit to wait for a backup officer. Trooper Cervantes then noticed Johnson begin to move around in the vehicle. Fearing Johnson would attempt to drive off and endanger the public, he attempted to arrest him. An altercation occurred when Johnson woke up and grabbed at Trooper Cervantes, who drew his firearm to force Johnson to comply. Johnson initially complied so Trooper Cervantes holstered his weapon. At this time Johnson lunged forward and grabbed a hold of Trooper Cervante's vest. Fearing he would be pushed into oncoming traffic, Trooper Cervantes drew his weapon and fired two shots, striking Johnson once. Trooper Cervantes removed Johnson from the vehicle and placed him into handcuffs, per proper procedure while waiting for backup to arrive to provide traffic control for emergency vehicles staging nearby,

Officials have placed the trooper who shot Johnson on paid administrative leave. The trooper was never charged with any foul play. The department also stated there is no dashcam video as both troopers involved were motorcycle officers and were not equipped with body cameras.^[2] However, video footage was later released from a live-feed Arizona Department of Transportation camera that was recorded by a local news station after the incident took place. The trooper was never charged or found to be at fault for the murder.^[6] The internal investigation by the Arizona Department of Public Safety was completed in April 2021, and concluded that there were no issues or deficiencies in the incident.^[4]

The Arizona Department of Public Safety erected fencing around its headquarters in Phoenix in late May 2020 in order to stop a vigil for Johnson on the grounds. The fencing has since been turned into a community mural of posters, cardboard and paper signs that were fixed to the fencing with string and tape.^{[citation needed]}

Johnson's death was protested by Black Lives Matter protestors along with the murder of George Floyd. On June 7, protestors had held 11 days of daily marches in Phoenix to demand change and chanted for six minutes straight to highlight the time that medical aid was withheld from Johnson even with an ambulance stationed a few hundred feet away.^{[citation needed]}

The family of Johnson and their attorney Jocquese Blackwell, have questioned how a man who was sleeping in his vehicle and disarmed could end up being killed, emphasizing the lack of body cameras, police cameras, or other witnesses to corroborate the sole police account of the incident.^[2]

Arizona State Representative Reginald Bolding, has demanded more transparency in the case and sent a letter to the public safety department.^[2] He later issued a statement to the US Department of Justice to take over the investigation, that was cosigned by Representative Doctor Geraldine Peten and Arizona Commissioner Sandra Kennedy.^[7]
