The investigation by the Harris County Sheriff’s office soon reached a dead end. It appeared that the family was well-liked and had no enemies.
The deaths baffled investigators. After six months, then-Sheriff Adrian Garcia turned to the public for clues, offering a $70,000 reward for information. Neighbors, along with Houston’s Chinese community helped raise money for the reward.
Then the case went cold.
It took eight years, seven months, and 17 days to develop the evidence and solve the Texas cold case. And Tuesday the current Harris County Sheriff, Ed Gonzalez was happy to announce his investigators had charged Lu with capital murder.

According to the sworn affidavit of investigator Timothy Hayes, it was a professional dispute between Sun and Lu that led to the murders. Both men were employees at a Houston oil and gas company, Cameron International.
Lu’s wife told investigators her husband and Sun disagreed about work. Lu wanted to get ahead at Cameron, but Sun “did not agree with the promotion.”
