SPRING, Texas — The Harris County Sheriff's Office released surveillance footage Tuesday morning showing two persons of interest after a couple was found bound and killed inside their Village of Northgate Forest home in Spring over the weekend, according to Sheriff Ed Gonzalez.
In the video, a black 2007 to 2014 Lincoln Navigator approaches the subdivision entrance around 8:20 p.m. Thursday and parks inside the turn around drive-way in front of the main gate. Two men exit the vehicle and then crawl under the gate, entering the subdivision.
Investigators said it's likely the victim, who have been identified Boa and Jenny Lam, both 61, pulled into their garage about 20 minutes later. Homicide detectives suspects the couple was ambushed inside their garage and then forced into their residence, where they were bound, robbed and murdered.
The sheriff's office said detectives also have footage of the couple's 2016 gray 4DR Porsche Panamera leaving the subdivision at 2:30 a.m. Sunday before returning again at 6:30 a.m. When it returned, the passenger left the Porsche and climbed into the driver's seat of the Lincoln Navigator before driving off.
The stolen car was found abandoned in a parking lot off FM 1960 on Sunday afternoon, deputies said.
Sheriff Gonzalez said the suspects returned to the Lams' home several times between the initial assault Thursday night and the discovery of the victims' bodies Saturday night.
Deputies responded to a wellness check in the 16500 block of Glorietta Turn around 6:50 p.m. Saturday after receiving a call from the victims' son. He and his sister hadn't had contact with the Lams since Thursday. The victims' cellphones were going straight to voicemail and their home phone was out of service. The son became concerned after knocking on the couple's door that night with no response, investigators said.
"It's important that our community works together to solve this horrific and brazen crime," Gonzalez said.
Although the house was secure, it was apparent, by looking through the windows, that the interior of the house had been ransacked; cabinets and drawers were open and items were thrown on the floor. When officers arrived, they were forced to break into the two-story home before finding the parents inside.
Both victims suffered had from gunshot wounds and the residence was ransacked, deputies said. The sheriff's office said an unknown number of firearms, jewelry and other valuable items, including the couple's Porsche, were missing.
“We’re asking the public that if you saw anything out of the ordinary to please call the Harris County Sheriff’s Office,” Sheriff Ed Gonzalez said.
The first suspect appears to be 6 feet 4 inches tall with an unusual gait or limp. He was wearing a letterman's jacket with "CC" on the front and two tone pants, with one light colored leg and one dark colored leg. His face was covered in the video.
The driver was of a medium height and build. His face was not covered in the video.
