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.
"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."
Some blamed the media for sensationalizing the deaths with repeated stories every day while others questioned why the sheriff's office had provided so little information. Most, however, said the deaths had not made them feel less safe or led to changes in daily habits.
According to his social media profiles, Sun had a doctorate from the University of Texas at Austin in engineering mechanics and worked as an analyst at Cameron, an oil field equipment manufacturer.
Garcia said the adults killed were naturalized Chinese immigrants who were "average residents in every way."
He said there is no apparent motive in the killings.
"It's not an everyday occurrence and obviously this is a great concern for us," Garcia said. "We want the public to rack their brains, and provide us any bit of information that they can."
All of the family members were shot at least once in the head and the Harris County medical examiner ruled all four deaths homicides on Monday.
