Timothy Xie Sun was 9 years old when he and his family were found shot to death in their Cypress, Texas home. The family—Timothy; his parents, Maoye Sun and Mei Xie; and his 7-year-old brother, Titus Sun—were discovered on January 30, 2014, each in separate rooms and each having been shot in the head in what investigators described as execution-style killings.

The case remained unsolved for years while authorities sought the public’s help. In September 2022 a former co-worker of Maoye Sun, Feng Lu, was arrested and charged with capital murder after DNA on Mei Xie’s purse was newly linked to him. Court documents say Lu had been disgruntled about not receiving a promotion and believed Maoye Sun had made derogatory comments about him to colleagues. The motive for the killings has not been fully explained.

Does anyone have information about the Sun family, their neighborhood in Cypress, or the workplace where Maoye Sun and Feng Lu were employed?
