A passenger in a vehicle going the wrong way on State Highway 114 in Southlake was killed when the car crashed into a concrete barrier early Monday morning.
Police said Cristian Leos, 18, crashed into a barrier wall along the 3000 block of SH 114 near Kimball Avenue at about 1:30 a.m., closing the road way for several hours.
Southlake city spokeswoman Kim Leach said Leos was driving eastbound in the westbound lanes. Several drivers called 911 to report a wrong-way car, Leach said.
The officers who responded tried to flag the vehicle over, but the driver sped up to faster than 100 mph, Leach said.
Leos' passenger, 18-year-old Bonifacio Leos, was killed in the crash.
"I believe the suspect and the victim in this are related, so you have the loss of a family member," Southlake Police Chief Stephen Mylett said. "It just ... did not need to happen."
In a statement released Monday, Mylett said the crash was a tragedy.
"A life was lost in this horrific accident, an accident that should have never occurred," he said. "At this point, we believe alcohol was involved."
Cristian Leos was taken to John Peter Smith Hospital in Fort Worth for treatment. He was later booked into the Keller jail on a charge of intoxication manslaughter. Police said he could face additional charges.
