"It's a senseless, senseless crime," said Thurber, who is employed at The Salt Lake Tribune as a sports clerk.
Zane was an adventurous, outgoing boy who crammed a lot of life into the three years he had, Thurber said during a Monday interview. He loved playing Peek-A-Boo, swimming and had "a real strong connection" with his mom, Thurber said.
Now the Thurbers need help paying for Zane's funeral, medical expenses and other costs. Relatives set up the Thurber Family Funeral & Medical Expense Fund at YouCaring.com, where, as of 11:30 a.m. Monday, they had received about $13,000 toward a goal of $50,000.
The family has also set up a fund at TransWest Credit Union, at 39 W. 2100 South, under the name Aubrey Thurber, Zane's mother.
In addition to Zane's death, the crash caused Matt Thurber to suffer a concussion, and knocked his 6-year-old son Holden's tooth out.
"It was just, very, very painful. I [have been] rear-ended before, but it was nothing like this. It was the most jolting feeling I've ever had," Thurber said. The airbags blew and he heard Holden scream for his brother.
"I was hoping that he was just knocked out, unconscious," he said. Thurber only learned after arriving at Intermountain Medical Center for his own injuries that his son had died.
A witness to the crash did not see Guinea's brake lights before his pick-up truck crashed, according to a probable cause statement. The impact caused a chain reaction that pushed the Thurbers' Subaru into the car in front of it, and so on, until five vehicles were involved in the accident.
After the crash, police said Guinea, 45, got out of his truck and tried to blend in with other witnesses that had stopped to help. One witness held him until police could arrive.
Police said they suspect alcohol was a factor in the crash and arrested Guinea on suspicion of automobile homicide and driving under the influence. A witness reported that Guinea smelled "like a bar," according to a jail probable cause statement.
Jail booking records also show there is an immigration hold on Guinea, who was being held at the Salt Lake County jail in lieu of $250,000 bail.
