LITTLE ROCK, Ark. /HAVERHILL, Mass. (CNN/WCVB/KTHV) - In today's C-Block, we take a look at a landmark case in Massachusetts where a man is believed to be the first person to be convicted of motor-vehicle-homicide because he was texting.

Negligent operation and injury from mobile phone use. Guilty or not guilty? Guilty.

The guilty verdicts against 18-year-old Aaron Deveau underscored the devastation suffered by the members of two families, collapsing in tears at opposite ends of the courthouse. The jury found that the teen caused the death of Daniel Bowley in February of 2011 because he was texting when he crashed into him head on.

Bowley died of his injuries 18-days-later.
