It happened around 11:15pm Saturday at the victim's home on Roydencrest, near Dawn Lilly in northwest Harris County.
Deputies say a family was returning home from a car dealership where they had just bought two new cars. The victim was in one car and his wife and child were in another car.
As soon as the man's family went inside the house, the suspects ambushed him and tried to steal one of his brand new vehicles. They shot him once in the chest.
Constables believe the suspects followed the family home from the dealership.
The man is expected to survive. The shooters remain on the loose.
