The crash happened on Interstate 10 near Chandler Boulevard on January 12. Officials originally said the crash may have been due to distracted driving.
On Thursday, DPS officials announced that a 36-year-old man has been arrested in connection to the crash after an investigation revealed he was actively using TikTok at the time of the crash.
The man, who was driving a tractor-trailer, told officials he received a message on his work tablet, acknowledged the message and when he looked up, saw that traffic was stopped but could not stop in time to avoid a crash.
His cell phone was turned over to law enforcement to conduct a forensic examination. It was then discovered he was using TikTok at the time of the crash.
Officials say the man was also driving 68 miles per hour in a 55 miles per hour work zone.
The man has been booked on charges including five counts of manslaughter, four counts of endangerment, and one count of tampering with physical evidence.
