The illegal alien who slammed into the rear end of the car 3-year-old Zane Thurber was riding in with his dad and older brother, was carrying a so-called 'driver's privilege card,' according to police.
Utah is one of a handful of states that offers a modified driver's license to illegal aliens.
The license, which does not require the applicant to have a Social Security number, must be renewed annually and costs $25.
The state began issuing the permits in 2005.
On Saturday night, Manuel de Jesus Guinea crashed his Dodge Ram pick up truck into a family's Subaru Legacy at an intersection in Taylorsville, according to police.
Guinea was reportedly traveling at a speed of about 70 mph, and never made an attempt to hit his breaks, the police report states.
Zane, who was in the backseat was pronounced dead at the scene.
The boy's father, Matt Holder, was knocked unconscious during the crash and did not learn of his son's fate until sometime after arriving at Intermountain Medical Center.
Zane's 7-year-old brother was also injured.
The Salt Lake Tribune reported:
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.
A witness reported that Guinea smelled "like a bar," according to a jail probable cause statement.
Guinea, who is in the country illegally from El Salvador has been charged with vehicular homicide and DUI with serious bodily injury. He is currently being held at the Salt Lake County Jail on an immigration detainer.
Though the Utah legislature promised that by issuing these 'driver privilege cards,' illegal aliens would then purchase auto insurance and be held accountable for their actions, Guinea had no insurance and the Zurber family is now asking for donations for Zane's funeral, as well as teh family's medical bills.
