Deputies have identified a husband and wife who were killed along with their children last month in their home in northwest Harris County.

Mei Xie and her husband Maoye Sun along with the couple's two sons were found dead at about 7:30 p.m. Jan. 30 in their home in the 14000 block of Fosters Creek Drive in Cypress, according to the Harris County Sheriff's Office.

Deputies said the sons' names have not been released because officials have not formally identified them through dental records. However, the Cypress-Fairbanks Independent School District has identified the children as 9-year-old Timothy Xie Sun and 7-year-old Titus Xiao Sun.

All the victims had been shot in the head and their deaths have been ruled homicides.

Deputies said the slayings have so far baffled investigators. They don't know what type of gun was used in the shootings, and they have not yet discovered a motive or suspect in the case.

Investigators said they were suspicious that a back door was open and one of the windows was broken, but they may be unconnected to the shootings.

The couple was last seen on Jan. 24. The boys were last seen at their school, Sampson Elementary, Jan. 23.

Cypress residents said the shooting deaths were unusual for the community.

"It's not what you'd expect," said Stephen DeMik, an associate pastor at St. John Lutheran Church and School. "If there were five or 10 a month then it'd be just another one. But here, it's not."

Anyone with information about the case is urged to contact the HCSO Homicide Unit at 713 967-5810 or Crime Stoppers of Houston at 713-222-TIPS.
