Authorities have released the name of the 18-year-old boy who died Thursday when he fell from a moving car in North Richland Hills.
Travis Hutton was identified by Friday morning by the Tarrant County medical examiner's office. His name was withheld earlier as officials awaited confirmation that his family had been notified.
Hutton was from Colleyville, said Investigator Keith Bauman, police spokesman.
Police were summoned at 7:39 p.m. Thursday to the incident in the 4800 block of Davis Boulevard, Bauman said.

Hutton was a front passenger in a white Mazda 6 four-door car driven by a 17-year-old boy from Grapevine, which had just exited Northeast Loop 820, Bauman said.
Responding officers learned Hutton, for unknown reasons, opened the passenger-side door and stood on the door frame, but he lost his grip and fell from the car, Bauman said.
Bauman said he did not know if Hutton came in contact with other vehicles but, he added, Hutton's injuries "were substantial" and he was pronounced dead at the scene.
There were two other passengers in the back seat, although Bauman said he had no information on them.
He said no one else was hurt.
The medical examiner's office reported that his death resulted from "fall and run over by motor vehicle."
Bauman said officers believe he was run over by the Mazda.
The investigation was continuing and officers were checking to see if other vehicles may have been involved, but Bauman had no information about that on Friday.
Hutton was a senior at Colleyville Heritage High School, said Megan Overman, spokeswoman for Grapevine Colleyville Independent School District.
"He has been in GCISD since elementary," she said. "We have crisis counselors at the school today to assist students and staff."
