Ibrahin Robles Ramos was 52 when he was shot and killed during a night shift at a Valero gas station in Mesa, Arizona, on May 31, 2013. A U.S. Army veteran who served 16 years and originally from San Juan, Puerto Rico, Robles was covering the shift at his son’s request. Minutes into the shift a man entered the store, approached the counter, and shot Robles in the abdomen; Robles was taken to Scottsdale Osborn Hospital where he later died. Nothing was taken from the register.

Surveillance footage later identified 20-year-old Keishaun Green entering the store and shooting Robles with a black semiautomatic handgun. After Green allegedly committed a second homicide on June 15, 2013, his arrest allowed ballistics testing to link the same gun to both killings. Green was convicted in February 2016 of first-degree murder and attempted armed robbery in Robles Ramos’s death and received life without parole, plus an additional consecutive 25-year sentence for the second murder. Reports say an uncle had warned authorities earlier that Green possessed a stolen firearm.

Did anyone in the area know Robles Ramos or notice suspicious activity at the Valero the night he was killed?
