Mass. Teen Aaron Deveau Faces Prison in Landmark Texting Homicide Case

Teenager Aaron Deveau insists he was not texting when his car swerved and collided head-on with an oncoming pickup truck on Feb. 20, 2011, but 18 days after the crash, the man he hit died.

Now Deveau is on trial in Haverhill, Mass. in what could be a landmark case in the controversial topic of texting while driving. Deveau now stands accused of killing 55-year-old Donald Bowley.

Prosecutors allege that Deveau, who has pleaded not guilty, was texting the day his vehicle slipped across the center line of a Haverhill street and crashed into Bowley's truck.

"My brother received such severe head trauma that he had, there was no hope for him," the victim's sister Donna Bowley told ABC News.

Deveau was charged with motor vehicle homicide by negligent operation, negligent operation of a motor vehicle, being an operator under 18 using a mobile phone, being an operator reading or sending an electronic message, a marked lanes violation, and two counts of negligent operation and injury from mobile phone use.
