Nicole Hutchison is out of jail on an intoxication manslaughter charge.
The man who died had only been hired for the job two weeks before, and his colleagues who witnessed the crash are devastated.
Hutchison says she was heading to her boyfriend's house just before 1 a.m. early Friday morning when she saw men standing in the road part of a work crew, swerved and then hit the barrier.
But investigators say she hit Bernard Armstrong, who suffered from massive internal injuries and died. He had been driving a crash cushion truck on the left shoulder.
"She certainly feels the loss and the devastation of what occurred," said Paul Johnson, Hutchison's attorney.
In the arrest warrant affidavit, one officer said 42-year-old Hutchison had "red, bloodshot eyes, the odor of an alcoholic beverage coming from her breath...and swayed while standing."
She refused a blood draw and breathalyzer and struggled with portions of the field sobriety test.
Officers described Hutchison's behavior as "very angry and verbally aggressive" and said she stated during the arrest "that she was wealthy and that the officers will regret this decision in court."
Johnson believes her remarks could be a result of the crash.
"Often times at the scene of an accident, you're going to have individuals who've been in an accident in pain, and an airbag explosion in your face and the impact of the accident and stress of the scene, you're going to have people who are disoriented," he said.
In the affidavit, "she admitted to drinking one glass of wine at the CLARK restaurant and one glass of wine at the TASTEMASTER's awards," held at the Empire Room in west Dallas.
The event ended at 10 p.m. and the accident happened almost three hours later as Hutchison told officers she was leaving her M Streets house, heading to her boyfriend's house in North Dallas.
Hutchison had three dogs in her SUV last Friday morning. During her police interview, "She asked numerous times about her dogs in the vehicle and did not display any concern regarding the crash or victim."
Hutchison's blood alcohol level was later drawn at the jail. It has not been released, but her lawyer says she suffered injuries to her arm, head and thigh and went to Parkland Hospital.
"That's going to be one of the main issues of this case: whether or not it was intoxication or whether or not it was disorientation as a result of the accident," said Johnson.
On various social media accounts, she lists herself as vice president of sales for a software company she founded.
Back in 2000, she pleaded not guilty for DWI and resisting arrest in Flower Mound.
She was acquitted by a jury and given two years' probation.
Armstrong, 60, was a TxDOT contractor working for Pannell Industries. He started April 29.
Colleagues describe him as "the sweetest man." He leaves behind a wife and children.
Armstrong's funeral is Tuesday.
