Lu asked Sun to recommend him for a transfer to the R&D department. And although Sun assured him that he had pushed for Lu to get the job he wanted. But the job never came through. And Lu blamed Sun.
In interviews after his arrest, Lu denies ever being inside the Suns’ home. He said he didn’t even know where he lived. He claims he never met Sun’s wife and children.
But his DNA was found on Mei Xie’s gray and black Coach purse at the murder scene.
An employee at Full Armor Firearms confirmed to investigators Lu bought a Glock 9mm handgun with 50 rounds of ammunition. Lu made the purchase on Jan. 23 and returned it on Feb. 4. It was returned without a barrel.
Analysts determined that the bullet taken from 7-year-old Titus Sun’s body and two bullets recovered from bedrooms at the Suns’ house have “design features that are physically consistent with bullets” Lu purchased in January 2014. And the bullet from the child’s body was “identified as having been manufactured on the same machine” as the ammo Lu had purchased at Full Armor, according to the Hayes affidavit.
Texas cold case solved
Andy Kahan of Crime Stoppers Houston said “For eight plus years he’s been on the run, and then he made a big mistake, and that’s why he is in custody waiting to be sent back. You’re looking at a capital murder charge. I would imagine it’s just a matter of time he’ll be back to face trial.”
