Mei Xie, 49, was one of four members of a Cypress, Texas family killed on February 3, 2014. Xie, her husband Maoye Sun, and their sons Timothy, 9, and Titus, 7, were found shot execution-style in their home, each with gunshot wounds to the head in what became known as the Cypress massacre.

Investigators linked a former coworker, 58-year-old Feng Lu, to the killings after newly tested DNA placed his profile on a purse belonging to Xie. Lu was arrested in San Francisco in September 2022 and charged with capital murder. Prosecutors reported evidence suggesting Lu had sought a promotion at Cameron International, believed Sun had made derogatory comments that impeded that effort, and that Lu had purchased a handgun shortly before the killings and later returned it without the barrel. Lu had previously denied knowing the family or their whereabouts.

Community groups expressed relief at the arrest after nearly nine years without resolution. Does anyone have information about the family or the workplace relationships at Cameron International that could shed light on this case?
