Mauricio Martinez, 27, was fatally shot in the parking lot of the Casa Del Rey Bar on the 200 block of W. Warner Avenue in Santa Ana just after midnight on April 11, 2017. He was found with a gunshot wound to his upper torso and was pronounced dead at the scene shortly before 12:30 a.m.

Police say the shooting followed an argument between Martinez and a 19-year-old, Augustin Ceja, who had recently moved from Mexico. The two were reportedly not previously acquainted and neither had gang ties. Witnesses described an SUV leaving the area immediately after the gunfire. Detectives later arrested Ceja and recovered a loaded handgun believed to match the caliber used in the killing; he was booked on suspicion of murder and held on $1 million bail.

What did witnesses in the bar or the parking lot see that night who haven’t yet come forward?
