The morning of the killing, the second camera — which has a time stamp more than three hours behind real time — captures Alfonso calmly washing dishes, going in and out of the kitchen.
But the couple had been squabbling since they woke up. At about 10 a.m., according to a Miami-Dade police arrest report, Alfonso was upstairs, and Medina pointed his .380-caliber pistol at her.
Alfonso said “she was leaving him,” according to the arrest report. The video, which has no sound, shows her returning to the kitchen.
