Coleman has pleaded not guilty to murder. Prosecutors showed an image of a handgun recovered from the scene.
"Could you tell if the firearm was loaded as it sat on the table?" the prosecutor asked.
"I believe there was a magazine inside," Fresno Police Officer Steven Excinia said.
Further testimony indicated the violence that day escalated quickly.
Johnson went to Coleman's Northwest Fresno home to look at fishing gear. Within moments, an argument occurred, followed by a shooting.
Fresno Police Department Corporal Sergio Gonzalez testified about statements from a witness.
"He started saying, 'He's here to kill us. He's here to kill us.' After that, she said that he wasn't right, and she noticed that Stewart had a handgun in one of his hands."
It is the second time prosecutors have presented their case. A judge ruled last year that there was enough evidence for the case to go to trial. That case was later dismissed, and a new case was filed, requiring a judge to hear the matter again.
"Your honor, I'd ask the court not to hold my client to answer. We don't believe the people have shown requisite malice aforethought," the public defender argued.
As officers testified, members of the victim's family watched from the courtroom gallery. The public defender also raised questions about Coleman's mental health, revealing he suffered from schizophrenia.
For the second time, a judge ruled that prosecutors presented sufficient evidence to proceed to trial.
Coleman is scheduled to return to court on July 28.
