Arrest made in 2014 murders of 4 family members, including 2 children, executed at NW Harris County home, authorities say

An arrest has been made eight years after a family of four was murdered inside their home in northwest Harris County.

HOUSTON – An arrest has been made eight years after a family of four was murdered inside their home in northwest Harris County.

Feng Lu, 58, has been charged with capital murder in the killings of the Sun family. He was arrested Sunday in San Francisco, California.

On Jan. 30, 2014, Homicide investigators with the Harris County Sheriff’s Office responded to a residence on Fosters Creek Drive in the Coles Crossing subdivision for a welfare check after receiving reports about an odor.

When deputies arrived and entered the home, they found four people lying dead in separate rooms. Each had been shot in the head. The victims were identified as husband and wife, Maoye Sun and Mei Xie, and their two sons, Timothy and Titus. The children were 9 and 7 years old, respectively.

According to court documents, a purse was found in the laundry room with items scattered on the floor.

Detectives interviewed the suspect at an unspecified time and collected a saliva sample, documents state.

Lu allegedly told authorities he did not know the wife and had never been to the victims’ home, and did not even know where they lived until they were murdered.

Detectives said the suspect bought a gun in January but returned it a few weeks later.

According to court documents, the suspect was working at Cameron International and tried to transfer to another department. He asked the husband, Maoye Sun, to give him a recommendation for transfer. Investigators said Lu told them he heard the husband did not provide a recommendation for the transfer so he called Maoye at work and asked him why.

Maoye reportedly said he did support the transfer. The suspect told authorities that Maoye also made derogatory comments about him to his fellow co-workers and that is why he did not get the promotion.

An employee at Full Armor Firearms told investigators Lu bought a 9mm handgun, along with a box of ammunition. When Lu returned the handgun to the store in February 2014, there was no barrel in the gun. Lu told the employee his wife threw the barrel away because she didn’t want a gun in the home, investigators said.

Police said Lu told them he lost the barrel of his handgun while he was cleaning it in a parking lot of a grocery store. He said when he returned the gun, he threw away the ammunition.

The suspect’s wife told police she knew about her husband’s disagreement with the victim at work and denied taking the gun barrel.

Investigators said they determined the bullets used in the shooting were consistent with bullets used with the gun he had purchased.

Lu is currently in a California jail waiting to be extradited to Texas.
