Driver killed after setting off chain of crashes on Katy Fwy had been hit moments prior: HPD

HOUSTON, Texas (KTRK) -- One person is dead after a fiery crash involving an 18-wheeler on the Katy Freeway in The Heights Monday morning, police said. It turns out that person may have been hit by someone else prior to hitting the big rig.

The crash happened at about 2:35 a.m., causing all mainlanes on the Katy Freeway outbound at Washington to close, according to Houston police. By 8:30 a.m., crews had cleared the scene.

The video above shows some of the aftermath of the wreck.

Houston police said a Chevy Impala was speeding on the freeway when it hit the back of a big rig. That set off a chain of several other cars crashing, including a pickup truck that bounced off a wall and hit the car that was initially speeding, according to police.

In an update, HPD said the Impala also had damage on its rear, meaning someone may have hit them from behind and drove off.

That car caught on fire and the driver inside died. Police did not release any information on the driver as they said the body was so badly burned.

Police are looking for the driver who fled but did not have any information on the suspect or the suspect's vehicle. If you saw what happened, officers are urging you to come forward.
