Police say a speeding car slammed into a tree after losing control along a Dallas roadway Sunday night, killing all six people inside.

Police spokeswoman Monica Cordova said a Chevrolet Impala was traveling southbound on Bonnie View Road when it crossed over Persimmon Road at a high speed at about 9:10 p.m.

Shortly after, the driver side rear tire of the vehicle hit the center median, police said. The 20-year-old driver lost control and the vehicle hit a tree in the median.

"I don't even know how to feel right now," a relative Marcelina Cantu said. "I don't know what to do. This is too much for me."

Police confirmed four people died at the scene, two teenage boys, two men and two women ranging in age from 15 to 23. Paramedics transported two people who survived the crash to the hospital, though they died a short time later.

Friends of the victims are stunned, many of them adding to makeshift memorial to them at the scene of the crash.



“It’s sad,” said Anjona McDonald. “They was young. They was young. All of them was young.”



Lynn Payne was driving right behind the car when the driver crashed.



“He was driving at a high rate of speed. I want to say he was doing at least 100 miles an hour,” Payne said. “I told my daughter, I said, 'Oh my god, if he don’t slow that car down something is going to happen.'”



Neighbors said drivers often speed down the winding road.



“It's all the time, every day,” said Willie Williams. “This might slow them up some, so I hope so.”

The Dallas Independent School District released the following statement Monday.

“Dallas ISD is deeply saddened to learn that three students at Justin F. Kimball High School have died as the result of a traffic accident on Aug. 30 [sic] in Oak Cliff. Grief counselors will be at Kimball and both T.W. Browne Middle School and Daniel Webster Elementary School, where siblings of the victims are enrolled, to help those school communities address this loss."

The names of the victims have not yet been released by the Dallas County medical examiner.

Cordova said speed was a factor in the crash, but not alcohol.
