Judge Denise Navarre Cubbon said that all four sentences were suspended in favour of the teens being sent to Toledo's Lucas County Youth Treatment Centre.
'It's a treatment facility, for certain services, to provide so these boys change their behaviour and can become productive members of our community,' she said.
Lillian Diallo, a lawyer for the Byrd family, called the decision outrageous.
"Suspended what? If you do what? So eight months you get to go home?" she told WTVG outside the courtroom.
"This child will never be at home. His son will never see him. His mother will never be able to say: "Hey son, how are you? How's your day?" Touch his face, see his face. This is outrageous."
According to ABC News, 30 letters were written on behalf of the victim calling for a strong punishment for the teens.
One of the boys read a letter in court apologising to the Byrd family.
"I pray for him and his family every single day and night and cannot imagine what they are going through and how they feel right now," the teen said.
Diallo was still angered by the suspended sentence.
"Let me tell you something - at the age of 10 you know if you take something and put it in a moving lane of traffic, you should know what the consequence will be," she said.
"You didn't take the sandbag and throw it on the side. You took that sandbag and you threw it down there to that boy's death."
Diallo, who knew the victim, said Byrd was planning a surprise proposal to his girlfriend, the mother of his 2-year-old son.
