Elena Flores was stopped at a light on Saturday when she was hit, causing her Saturn SUV to roll over.
She was early to pick up her daughter from work two miles away, but she never showed.
Her daughter, Sandi, got a ride home and unknowingly witnessed the accident's aftermath.
"No one called me to tell me she had gotten into a wreck," said Sandi. "I saw it for myself."
She recognized the SUV. Police told Sandi her mother had been taken to Harris Methodist Hospital following the crash.
Elena, 46, was pronounced dead.
The mother of two emigrated from Mexico to Fort Worth 20 years ago.
She worked as a nanny and housekeeper and was a devoted Jehovah's Witness, spending her last hours of life with friends.
Fort Worth police arrested the driver of the other vehicle involved in the crash, 22-year-old Luke Reed, for suspicion of intoxication manslaughter. His passenger, 23-year-old John Morgan, was arrested for suspicion of public intoxication.
Both are out of jail on bond and seniors at TCU.
"You took my mom away from me," said Sandi. "She was my world, she was my best friend and you took her away from me because you wanted to have fun and thought it would be a good idea to drink and drive."
Investigators have not released Reed's and Morgan's blood alcohol levels.
TCU confirms Morgan is a business major and member of the Sigma Alpha Epsilon fraternity.
Reed is a criminal justice major and a former SAE member.
Sandi and her brother, Luis, hope their mother's death isn't forgotten.
"Every time they look at their mom, they're gonna know they took someone's mom away," said Sandi.
Elena's funeral will be held Wednesday at her church.
A witness told TCU 360 that Reed admitted to being drunk, but police are not conclusively saying that.
