Deputies searching for chase suspect who crashed into a family in NW Harris Co.

HOUSTON, Texas (KTRK) -- Deputies are searching for a carjacking suspect who crashed into a family of six while leading authorities on a high speed chase in northwest Harris County.

The Harris County Precinct 4 Constable's Office said around midnight a deputy spotted a car matching a vehicle description that was reported stolen at gunpoint from a Walmart parking lot on West Road.

According to deputies, the car owner was pistol-whipped twice before the suspect took off in his car and drove off.

Once deputies spotted the vehicle, they tried to conduct a traffic stop, but the carjacking suspect fled. At one point, his speed reached 100 mph.

The stolen car collided with another vehicle. Inside that car was a family of six -- two adults and four children.

No one was injured in the crash. The driver of the stolen car got away on foot.

Deputies are still searching for that suspect
