The Boone County Sheriff’s Office in Indiana shared a semi truck driver’s handwritten apology after he plowed into slowing traffic on Sunday, killing three people and leaving over a dozen injured.
The driver was not suspected to be intoxicated while driving, but claimed he “looked down to set his coffee cup down” moments before the accident, police said.
According to the sheriff’s office, the accident occurred on Sunday morning on I-65 northbound around 11 a.m. and involved eight vehicles.

“A sad day for two Boone County families. The loss of two young women and a one-year-old child,” Boone County Sheriff Mike Nielsen said in a statement. “Distracted driving or driver inattention is a major cause of many accidents on our public roadways.
“In this case, we believe it was a contributing factor in this fatal crash. The Boone County Sheriff’s Office feels strongly that those that cause death on our public roadways, because of driver inattention, should be held accountable.”

“When tragedies like this strike, we must take into account the families of the victims, the family of Mr. Small and the numerous agencies all working together to figure out what transpired, and why,” the sheriff’s office wrote on Facebook. “Having said that, we ask that you give us time to compile data and complete a very thorough investigation before any other information is conveyed. Thank you.”
“Please pay attention to your driving when operating a motor vehicle,” Nielsen implored. “Give yourself plenty of room to have a way out, put down your phone or other objects, DO NOT drive distracted or impaired!”
