On January 30, 2014, Maoye Sun, Mei Xie and their sons, 9-year-old Timothy Sun and 7-year-old Titus Xiao Sun, were found shot to death in their Cypress, Texas, home. The Harris County Sheriff’s Office opened an investigation but struggled to identify conclusive evidence or suspects in the months that followed.

The killings touched the local Chinese-American community; the Houston Chinese Alliance organized a vigil for the family. Reports said investigators considered a former co-worker of Maoye Sun as a possible suspect and later pursued new forensic leads linking DNA evidence to an item belonging to Mei Xie.

The case remains unresolved in many respects as authorities work to establish the full circumstances and motive. Does anyone have information about the Sun family’s activities or contacts in Cypress around January 2014 that could help the investigation?
