Thu Lan Tran, 49, was shot and killed while working at a security business on the 5600 block of 28th Street in Sacramento on June 27, 2014. The assailant entered the office during a robbery and shot her in the head behind her ear, then fled with her laptop bag containing cash, paychecks, and checkbooks. A nearby shop owner found Tran in a pool of blood, followed the suspect and provided police with a partial license plate number that led to an arrest at an apartment near 32nd and X streets.

Nineteen-year-old David Alberto Romero was charged with first-degree murder with the special circumstance of committing the crime during a robbery. A jury found him guilty and the court found he had used a firearm in the offense. Sentencing was scheduled for June 19, 2015.

Tran was remembered as a dedicated mother of two and a respected member of her workplace. Does anyone have information about her life or the business on 28th Street that might shed light on what happened that day?
