A verbal dispute in a Tucson parking lot escalated into a deadly shooting on the evening of November 15, 2020. Thirty-year-old Luis Barraza-Bautista followed a man he had argued with after that man, identified as 54-year-old Pedro Garcia Martinez, drove away in a red pickup. While on a 911 call reporting Martinez’s license plate, Barraza-Bautista’s line went silent and gunshots were heard. Callers then reported gunfire and a vehicle crashing into a house in the 3000 block of E. Via Genovesa.

Officers found Barraza-Bautista with life-threatening gunshot wounds in his vehicle; he was taken to Banner University Medical Center and died of his injuries on November 18, 2020. Police located and detained Martinez the next day near E. Golf Links Rd. and S. Craycroft Rd.; he was interviewed and charged with second-degree murder in connection with the shooting.

What information about the moments before the shooting or any witnesses hasn’t been made public that could help clarify what happened?
