A fourth teenager has been sentenced for his role in the 2009 beating death of a Dallas-area man.
Prosecutors say 18-year-old Travis Joel Harmon of Celina was operating a truck involved in the reckless driving dispute.
Jonathan Bird of Wylie was attacked after telling several youths to slow down while driving through the neighborhood. According to police, Bird had gotten into an argument with several teens who were driving recklessly through a neighborhood. The teens and Bird exchanged words until the situation escalated into violence.
Harmon pleaded guilty to manslaughter and was sentenced Wednesday to six months in jail and 10 years of deferred adjudication probation.
The Dallas Morning News reports Harmon, who apologized to the victim's family, must also pay the funeral costs.
Harmon is dyslexic and has been diagnosed with Asperger's syndrome.
Three other teens have been sentenced over Bird's death, with penalties ranging from probation to 24 years. Another youth who pleaded guilty awaits sentencing.
Seth Dorris, 18, was the first teen found guilty for his role in the death of 28-year-old Jonathan Bird.
Dorris, who was originally charged with murder, will spend 20 years behind bars.
