Abdallah Khader was 2 years old when he was hurt in the 2009 crash on Cooper Street. He had been in a deep coma since then.
At the time of the crash, police arrested Stewart Richardson of Iowa for intoxication assault. They said his blood alcohol level was three times the legal limit for driving.
Richardson has a history of DWI convictions in other states, but has yet to be tried in this case because of delays and legal battles.
In 2010, Abdallah's mother stood with police and legislators who were trying to push through new laws that would increase the penalties for habitual DWI offenders.
Prosecutors say the 8-year-old's death won't prompt them to increase the charges Richardson faces to manslaughter.
He already faces a punishment of life in prison and is still in the Tarrant County Jail.
Abdallah's family wants people to understand how their son suffered.
"There's no more pain, no more suffering, no more medicine no more machines," said Abdallah's mother, Loubna Elharazin. "I feel at ease now. He is with God. He's an angel in heaven"
Elharazin says she forgives Richardson, but still wants him to be punished.
"I also want to free myself of Stewart Richardson," said Elharazin. "He's not gonna haunt me anymore. I want to tell him that I forgive him because my son now in heaven…that does not mean I do not want punishment for Stewart Richardson. I'm still going to go through the trial. I'm still going to want higher punishment, because he deserves higher punishment. He hurt so many people before."
