One person was killed and another seriously injured in a rollover accident Friday morning on U.S. 287 at Harmon Road at about 6 a.m., authorities said.
MedStar spokesman Matt Zavadsky said the second patient was taken to John Peter Smith Hospital in Fort Worth.
According to a Fort Worth police report, a vehicle flipped over and blocked U.S. 287 southbound. Zavadsky said one patient had to be extricated from a vehicle.
The highway was closed at about 6:35 a.m., WFAA reported.
Police said officers were still investigating as of 7:45 a.m.
WFAA and CBS DFW also reported two people were killed in a crash in Garland, in the westbound lanes of the LBJ Freeway near Jupiter Road.
Garland police told WFAA a Mitsubishi was heading west on U.S. 635 at a high rate of speed when the driver lost control. The car hit the inside barrier wall, near the HOV lane, and came to a stop. A woman and man were inside the vehicle, though it's not clear who was driving.
The woman got out of the vehicle, police say, and a Good Samaritan stopped to help. A Toyota then hit the Mitsubishi, the woman, and the Good Samaritan, according to WFAA.
Both were killed.
The Toyota stopped on the right side of the highway and caught fire, police say. The female driver was able to get out and was taken to the hospital.
The condition of the man inside the Mitsubishi was unknown. Police suspect the driver of the Toyota may have been drinking, WFAA reported.
