A Clayton County Superior Court jury has found Jamall Decarlos Mathis guilty on all charges against him -- except malice murder -- in the 2009 death of his young son.
The jury reached a verdict on Friday, according to Clayton County District Attorney Tracy Graham Lawson.
Lawson said Mathis will receive the maximum sentence of life without parole, plus 41 years.
Mathis' charges included felony murder, battery, aggravated assault, cruelty to children, and aggravated battery, according to a Clayton County Superior Court indictment.
Mathis, 20, brutally murdered his 17-month-old son, Ja'Mari Myckahi Jones, on Sept. 17, 2009.
"I am extremely pleased that justice was served...I am happy for the family," said Lawson, of the verdict.
Defense Attorney, Leon Hicks, had little comment regarding the verdict or the case, on Friday. "The jury has spoken," said Hicks.
"This was a calculated murder...quite frankly," said Executive Assistant District Attorney Lalaine Briones, during closing arguments, on Wednesday.
The warrant said the incident occurred on Iron Gate Boulevard, in Jonesboro.
"The accused did maliciously cause Jamari Jones, a child under 18, cruel [and] excessive physical and mental pain, by hitting him about his head and body with a blunt object and/or his hands ...," according to the arrest warrant in the case.
The trauma caused massive skull fractures, swelling to the brain, and hemorrhaging, the warrant stated. According to the indictment, Mathis also caused injury to the child's right arm.
"Jamari Jones was declared brain dead," the warrant said. It added that Mathis' acts caused the child's death.
