A Texas law firm is offering a $100,000 reward for information leading to the arrest and felony conviction of a hit-and-run driver whose 18-wheeler triggered a fatal crash that killed a Dallas father more than two months ago.

The Bison Law Firm announced the reward this week in an effort to identify the driver who fled after causing a four-vehicle collision on the northbound Dallas North Tollway near Spring Creek Parkway on October 21.

Investigators with the Texas Department of Public Safety said a white 18-wheeler towing a white dump trailer made an unsafe lane change just before 6 a.m., striking a Honda Civic driven by 47-year-old Juan Quiroz. The impact sent Quiroz’s vehicle into a concrete wall, where it rolled over. A Ram 1500 and a Toyota Camry then collided with the Honda.

Quiroz, who was heading to work, was pronounced dead at the scene. The other drivers were not seriously injured.

Authorities said the truck lacked visible company logos or a license plate, complicating efforts to identify it. It may have damage to the right side of the front bumper or the front right fender.

A limited image of the vehicle has been released and is now included on a wanted sign distributed by the law firm.

Brock Duke, an attorney with Bison Law Firm representing Quiroz’s family, said the reward is intended to encourage witnesses to come forward.

“To get some answers for this family, some closure. Who did this? Why did it occur, and why is nobody coming forward and taking responsibility for what happened to this family?” Duke said, per WFAA.

Quiroz’s daughter, Lama Quiroz, said the family has struggled through the holidays without him, describing her father as the heart of their home. She called him “a caretaker, a protector, someone who always worked and fought for the people he cared about.”

“Not as many laughs, not as many smiles,” she told CBS News Texas. “He would always have some dumb joke ready to tell.”

Lama Quiroz said the uncertainty lingers painfully.

“It feels like we’re waiting for a call that I’ll never get,” she said.

She expressed a desire to learn more about the incident, including “The identity of the driver — maybe where they were going, what they were doing, why they made that choice to just drive off like that.”

While she has forgiven the driver, Lama Quiroz emphasized the need for consequences.

“There’s no anger or hatred,” she said, per CBS News Texas. “But you broke the law, and justice has to be done.”

Asked if it gives her hope, she said, “yes,” adding, “Hopefully we can hear some answers soon.”

Video of the crash captured by the North Texas Tollway Authority has not been made public, as the Department of Public Safety cited the ongoing criminal investigation.
