A night of fun ended in tragedy for a group of sisters in Calallen last week.

Officials with the Texas Department of Public Safety said 21-year-old Tamara Wilburn was driving southbound Dec. 6 on County Road 69 near Hazel Bazelmore Park in a Ford Focus with her two sisters to pick up dinner.

At about 7 p.m., Savannah and Cebrina Tellez, ages 12 and 13, respectively, were riding on the hood of the car when Wilburn suddenly braked, DPS officials said. The two girls were both thrown from the hood of the vehicle, which resulted in Cebrina Tellez hitting the back of her head on the road.

The teenager was pronounced dead at the scene at 7:54 p.m., DPS officials said.

Savannah Tellez was transported to Driscoll Children's Hospital with incapacitating injuries, but has since been released.

School officials at Orange Grove Junior High School, where Cebrina Tellez was a seventh grader, said counselors from across the district, as well as pastors from nearby churches, were brought in to help students deal with the grief of Tellez's death.

"We're a small school, so of course everyone knows each other here," said junior high principal Arnold Diaz. "It's kind of shocking to hear that she was involved in an accident in which she was killed."

DPS officials said Monday no charges would be filed against Wilburn in connection with the accident.
