“It happened really quick. The altercation down the street. Apparently there was a disagreement between two people and it escalated really fast,” he said.

Surveillance video shows Locelvira walking some dogs, then arguing with Gaidos right before the shooting.

Officials said the victim was delivering flowers and made a comment to a man passing by. The verbal exchange ended with the victim hurling the vase and the suspect firing a gun.
