More than 20 deputies from the Bartow County Sheriff's Office lined the courtroom, including down both sides of the aisle and around the jury and defendants as the verdict was read.
Before the verdict was published, Judge Scott Smith told audience members that he understood that tensions were running high but he would not tolerate outbursts in his courtroom.
"It is troubling to me to see the violence in the outside world," Smith said. "But this is the one room that deserves dignity and respect, and there will be no violence in this room."
Smith also said the jury does not deserve to have the dignity of their verdict questioned, and if anyone could not control themselves, they would be arrested and held in contempt of court.
Castle and Jackson were found not guilty on count one of murder and guilty on counts two through five of felony murder, aggravated assault, battery and possession of a firearm during the commission of a crime.
Castle and Jackson, along with their cousin Leondris Tyree "Frog" Jackson -- who is currently on trial in Juvenile Court, were accused of shooting Norman Ray Moore Jr., 19, during a gang altercation at a 44 Middlebrook Drive party.
Witnesses told the jury various, conflicting recollections of the fatal night. Some statements related that only one of the defendants had a gun while others said they both were in possession of firearms.
Some of those witnesses acknowledged gang affiliations, saying Moore and his cousin called out "On the E" -- representing the EastSide gang -- and partygoers as saying "BBS," which is believed to represent a gang called Bottom Boyz Survivors.
Moore was, according to witnesses, pistol-whipped and struck in the facial area numerous times, leaving an abrasion on the right temple above the eyebrow and both the upper and lower lips possibly caused by impact of the victim's teeth.
Two bullets entered into Moore's left forearm and chest area, leaving exit wounds on the opposite side of his body. The bullet that entered Moore's chest pierced through his heart, both lungs and liver. Medical examiners said the significant loss of blood resulted in Moore's almost instantaneous death.
Castle and Jackson tentatively are set to be sentenced Dec. 13 in Bartow Superior Court. Both are currently in custody at the Bartow County Jail awaiting a pre-sentence investigation and sentencing.
