The evening of Jan. 25, a witness says Guinea was speeding west on 5400 South, weaving in and out of traffic, according to the charges. He then crashed into the back of a Subaru that was stopping for a red light at 1300 West, the charges add.
The investigation revealed that Guinea was traveling at more than 60 mph less than a second before rear-ending the Subaru, according to the charges. The speed limit for the area is 45 mph.
A 3-year-old who was restrained in the backseat, Zane Thurber, died later that night.
The crash caused a domino effect, forcing the Subaru into the car in front of it, then that car into the one in front of it, and so on, until a total of five vehicles were involved in the crash. Including the two people in the front seats of the Subaru, nine people were injured, according to the charges.
After the crash, police said Guinea 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.
Guinea does not have a court appearance scheduled yet.
