The looter convicted of murdering a retired St. Louis police captain during riots that unfolded after George Floyd’s killing is expected to be sentenced on Tuesday. 

Stephan Cannon, 26, was found guilty in July of first-degree murder in the death of 77-year-old retired St. Louis police Capt. David Dorn. 

Dorn was fatally shot while investigating alarms at a friend’s pawn shop on June 2, 2020. The retired captain fired warning shots into the air to disperse looters who were ransacking the business as he approached the building. Prosecutors argued that Cannon deliberated his actions when he walked to a corner near the pawn shop and fired 10 shots at Dorn.

Cannon’s attorneys argued the state had not provided any physical evidence linking him to the shooting and based their case largely on testimony from an unreliable witness, the St. Louis Post-Dispatch reported. However, prosecutors said Cannon was the only person standing on a nearby corner from where the shots originated.

After the slaying, investigators reportedly recovered a pistol, televisions and pieces of Cannon’s dreadlocks from an apartment where he was staying, but law enforcement did not locate the handgun that Cannon is believed to have used in the shooting.

Lead prosecutor, Marvin Teer, told jurors in July that Cannon deliberated before he shot “a good man who dedicated his entire life to doing nothing but helping others.”

Cannon’s lawyer, Brian Horneyer, said in his closing argument that police had “tunnel vision” when they charged Cannon without any physical evidence. He also said the state’s main witness, Mark Jackson, lied to police several times about the shooting and then made a deal to testify against Cannon.
