( CNN ) -- A Massachusetts teen was convicted Wednesday of homicide as a result of texting while driving and will serve one year in prison . In a landmark case for the state , Aaron Deveau , 18 , was found guilty on charges of vehicular homicide , texting while driving and negligent operation of a motor vehicle in a 2011 crash that fatally injured Donald Bowley , 55 , of Danville , New Hampshire , and seriously injured a passenger in Bowley 's car . `` I made a mistake , '' Deveau said Wednesday after his mother told the district court in Haverhill , Massachusetts he would not intentionally hurt anyone . `` If I could take it back , I would take it back . '' Judge Stephen Abany sentenced the teen to two and a half years on the vehicular homicide charge and two years on the texting and causing injury charge . He will serve one year concurrently on both charges and the balance of both charges is suspended for five years . His license will be suspended for 15 years . `` There are no winners today , '' Essex County District Attorney Jonathan Blodgett said in a statement . `` A beloved grandfather is dead . A once active woman can no longer work and is still racked with pain from her injuries and a young man is going to jail . When we get behind the wheel of a car , we are obligated to drive with care . ... As we saw in this case , in a split second , many lives are forever changed . '' The risks of texting while driving . In the February 20 , 2011 , accident , prosecutors said , Deveau 's car crossed the center line on a street in Haverhill , which is in northeast Massachusetts near New Hampshire , and hit the vehicle Bowley was driving . Bowley 's girlfriend , Luz Roman , 59 , was in his car with him and suffered serious injuries . Haverhill Detective Thomas Howell testified the impact left the two `` almost folded into the floorboards . '' Bowley died March 10 , 2011 , after he was taken off life support . `` My brother received such head trauma that ... there was no hope for him , '' Bowley 's sister , Donna Burleigh , said in court . Roman talked about the incident 's continued impact . `` Loss of sleeping , loss of my boyfriend . So many losses , I ca n't tell you how many , '' she told the judge . Essex Assistant District Attorney Ashlee Logan argued that Deveau may have erased some of his texts or lied to police after the accident about when he was texting . Deveau said after the crash in a taped interview with police , which was played in court , `` I was tired . I was distracted . When I looked away for one quick second , I came too close to her and I was trying to hit my brakes . '' His defense lawyer said authorities set out from the beginning to link texting to the crash , a cause-and-effect relationship that he contends is not valid . Some 38 states ban text messaging for all drivers , while 31 prohibit all cell phone use by `` novice drivers , '' according to the Governor 's Highway Safety Association . 2011 : NTSB urges ban on use of phones while driving .
