A standoff between police and a suspect in the shootings ensued after a brief car chase. Police brought in two trucks and wedged the suspect's vehicle between them on a cul-de-sac near the site of the shooting.
Harris County Precinct 4 Assistant Chief Deputy Mark Herman told ABC station KTRK this was a "domestic disturbance."
According to police, a woman at the 711 Leaflet Lane house who was shot said a family member was responsible and that person had left to kill another family member who worked at a nearby restaurant. Police were able to intercept the suspect before he got to the restaurant. When police arrived at the home, they found two adults and three children had been killed. \
A fourth child died after being airlifted to a hospital, said police. The woman who was shot was listed in critical condition at a local hospital.
The suspect was locked in the vehicle, visibly engaging with police from the driver's seat as of 9:00 p.m. CT. Police said the suspect, in his mid-40s, had a handgun and was holding it to his head. They were speaking with the man by cell phone as darkness fell over the scene. Nearby homes were evacuated.
