Police said the victim's friend told officers that the victim was asking Jonathan Dale Crenshaw, 45, for directions when Crenshaw pulled out a sharp object and stabbed the victim.
It noted that Crenshaw is a popular fixture in the area and is known for painting canvases along a trendy spot in the neighbourhood of South Beach in the city of Miami Beach.
Police said there were no indications that Crenshaw was under the influence of drugs or alcohol at the time of the incident.
Neither men dispute that Coronado was stabbed, but Crenshaw said he was attacked first, according to the arrest report.
That's when Crenshaw allegedly reacted by jumping up, stabbing Coronado and running away, police said. After stabbing him, he says he placed the scissors in his waistband and walked away from the scene.
Police arrested and charged Jonathan Crenshaw with aggravated battery.
Barrientos described the attacker to police as a homeless man with no arms.
He was taken to the hospital.
Crenshaw has an extensive criminal past, including battery of law enforcement officers, according to the Miami Beach Police Department.
Crenshaw has a court date on July 18; his bond has been set at $7,500.
