On the afternoon of Monday, February 1, 2016, 23-year-old Julian Jay Thomas was seated in his Chevrolet Impala at an Arco gas station at 3601 Center Street in Tacoma, Washington, when a man approached the car and opened fire. The shooter emptied multiple magazines—about 48 rounds—reloading several times; Thomas was struck at least 10 times and died. Two women who had been in the vehicle escaped unharmed and hid. The attack shattered the glass front of the busy AM-PM convenience store, but bystanders were not physically injured.

Investigators identified the suspect as 29-year-old Robert Deshawn Grott and described a motive tied to a months-long dispute over a missing handgun and prior shootings allegedly linked to Thomas. Prosecutors charged Grott with first-degree murder and accused his younger brother, Rashaad Dominque Grott, of driving him out of state. After turning himself in, Grott was tried; a jury convicted him of second-degree murder and multiple counts of first-degree assault. A judge later sentenced him to more than 50 years in prison.

Did anyone witness interactions between Thomas and the Grott brothers before the gas-station shooting or have information about the dispute over the missing handgun?
