Jocelyn Rangel was an oldest daughter who cared for her younger siblings and wanted to become a police officer.
The 21-year-old was studying at Tarrant County College.
But the former Castleberry High School student was killed Wednesday morning when she lost control of her car on rain-slick Northwest 28th Street and crashed into a dump truck.
"She was responsible daughter," her mother, Rose Maria Cabrera said Thursday fighting back tears as she spoke in Spanish. "And she cared so much for her little brother and sister."
Her daughter died at the scene Wednesday morning, according to officials at the Tarrant County medical examiner's office.
Cabrera said her daughter was headed to work at Unity One Credit Union at the time of the accident.
Rangel was driving a gray 2001 Mercury Mountaineer east in the 800 block of Northwest 28th Street, possibly at a high rate of speed, according to an initial police report.
At some point, the Mercury's left tire hit the curb of a center median, causing Rangel lose control of the car, police said.
On impact, the car began to spin, crossed the median and into the westbound lanes, where the vehicle hit a dump truck, police said.
The driver of the dump truck stopped and was interviewed by officers. The driver was not injured.
Cabrera said her 21-year-old daughter lived with her and had worked at Unity One for the last two years.
Rangel was a graduate of Castleberry High School, a school official said Thursday.
While she worked, Rangel attended classes at Tarrant County College-Northwest and the Trinity River campuses, according to TCC records.
"Happy is how I would best describe her," her mother said through her tears. "I can't believe this has happened."
Funeral services are pending for Rangel.
