Travis Lee Hodges is facing charges of intoxication manslaughter and intoxication assault.
Investigators say early Friday morning, Hodges took the westbound ramp to 183 off of Loop 12 too fast and flipped into an embankment.
Alicia Rodriguez, a 27-year-old makeup artist from Grand Prairie, was a passenger in the car. She was thrown from the backseat and killed.
The arrest affidavit says that Hodges told police he only had two beers the night of the crash.
Even though police say there were signs he was drunk at the time, there are several reasons they did not arrest him at the hospital.
"There are times when we'll make an arrest right then and there," said Officer James McLellan with the Irving Police Department. "In this particular case, it was complicated by the fact he was injured as well and needed medical treatment, and during our initial contact with him, the driver was cooperative with us."
Rodriguez graduated from South Grand Prairie High School in 2006, then immediately pursued her passion of makeup, working at Sephora, Ulta and most recently, Beauty Brands.
Friends say she loved animals and adopted as many strays as she could.
"We're all trying to handle it the best we can because it's really unfortunate and we don't know [Hodges]," said her friend, Kristen Brown. "I don't know him."
Rodriguez's funeral will be held Saturday in Grand Prairie.
Her boyfriend, who was also in the backseat at the time of the crash, was injured but survived.
