CONROE, Texas – A 16-year-old girl died after a single-vehicle crash in Montgomery County Wednesday morning. The vehicle’s 18-year-old male driver was in critical condition, DPS troopers said.

It happened just after 2 a.m. in the 12800 block of FM 1485.

Troopers arrived at the scene to find a 2002 Saturn nearly split in two, smashed into the side of a pair of utility poles.

The impact of the crash snapped both poles and tore up the power lines above.

Caney Creek firefighters called for additional help from the River Plantation Fire Department. It took crews almost 45 minutes to remove both occupants of the mangled vehicle.

Fog prevented a medical helicopter from responding to the scene. The driver was taken via ground ambulance to Ben Taub, and the passenger was taken to Memorial Hermann in Houston with severe head trauma, internal injuries and broken bones. She was pronounced dead at the hospital later Wednesday morning.

Entergy workers stood by while crews extricated the teens, waiting to repair the power lines and restore service to the area.

Troopers said they believe speed may have been a factor in the crash.

"It looks like he may have been traveling at a high rate of speed coming around the corner, and then he lost control of the vehicle," a trooper at the scene said.

The posted speed limit on that stretch of road is 50 mph.

Investigators did not release the name of either teen.
