A Texas couple was bound and shot to death in a home invasion in a gated community, according to police.

Bao and Jenny Lam, both 61, were found dead late Saturday at a Spring residence after their son couldn’t reach them for two days and alerted authorities, according to the Houston Chronicle.

Officers said they forced entry into the home and discovered the pair with fatal wounds and their home ransacked.

Authorities suspect the couple was ambushed when they parked their car around 9 p.m. Thursday in the garage.

“This may have happened any time after Thursday,” Harris County Sheriff Ed Gonzalez told the Houston Chronicle. “It appears that was the last time of contact.”

Anyone with information in the case is asked to call investigators at 713-274-9100.
