A mother died after being shot inside her vehicle just after 9 p.m. Monday night.
Police said the woman was with her husband and their baby at a Walmart in Stafford.
Shortly after, the family was involved in a hit-and-run accident.
The family's SUV was hit and the driver of the other car took off.
The family decided to follow the vehicle to a parking lot on Murphy Road near UP 59 when someone in the suspect vehicle fired shots.
The woman, sitting in her vehicle, was hit and died on her way to hospital.
Houston police and Stafford police are investigating, and say the suspect vehicle involved in the hit-and-run and shooting matched the description of a vehicle taken during a carjacking earlier in the evening.
They are looking for a green Jeep Commander with several men inside.
