At about 3:43 p.m., three catalytic converter theft suspects led deputies into a chase on the eastbound lanes of State Highway 99 at Gleannloch Forest Road.
The suspects lost control of their car, flipped, struck several trees, then caught on fire, according to Captain James Blackledge with the Harris County Constable Precinct 4.
"The vehicle, after impact, did catch on fire," Captain Blackledge said. "We only had one unit. He was within view of them when they crashed. He quickly did exit the vehicle, pulled the one male that was still alive out, and extinguished the vehicle with a fire extinguisher."
The injured suspect was taken by Life Flight in critical condition. No law enforcement was injured.
Herman said catalytic converters were recovered at the scene.
