A single-vehicle wreck killed a Watauga woman overnight in Haltom City, police said.
Terijo Kohler, 49, was identified by the Tarrant County medical examiner's office.
She was pronounced dead at the scene of the wreck in the 4000 block of U.S. 377, also called the Denton Highway. The area is the highway's intersection with South Diamond Oaks Drive, west of Diamond Oaks Country Club.
Accident investigators were called to the scene around 1 a.m., said Sgt. Terry Stayer, police spokeswoman.
Kohler was driving a Kia Sophia four-door car which was northbound on the highway, Stayer said.
Investigators determined that the car, for unknown reasons, went out of control and then crossed both the northbound and southbound lanes, Stayer said.
The car "ultimately went into a concrete drainage and went airborne," Stayer added.
Next, she said, the car struck a tree and the impact sent it spinning.
"It appears it rolled several times after striking the tree," Stayer said. "Everything we have indicates she wasn't wearing a seat belt. She was ejected."
There was no evidence of alcohol in the wreckage, Stayer noted.
"Somehow she lost control of the vehicle," Stayer said. "We don't know at this point what the cause was."
