Jones wept in the courtroom after he tried to speak about the incident but was cut off by the judge who said it wasn't the time to sort out the facts of the case. Jones faces anywhere from two years to life in prison if convicted on the counts he faces.
The two younger teens face life in prison without parole if convicted on the murder charge.
"I'm appalled," Hicks said after the hearing. "This is not supposed to happen in this community."
In court, Hicks said Luna was sitting in the back seat of a car when he pulled the trigger on a .22 caliber revolver and shot Lane once in the back. Hicks said Jones was driving the vehicle and Edwards was in the passenger seat.
A recording of an emergency call obtained Tuesday by The Associated Press offers a chilling account of the next moments as a woman identifying herself as Joyce Smith tells the operator she saw Lane fall over into a ditch as she drove by.
"He's got blood on his back," the woman says.
Edwards has had prior run-ins with the law and came to court Friday — apparently after the shooting — to sign documents related to his juvenile probation.
"I believe this man is a threat to the community and should not be let out," Hicks said as he requested Edwards be held without bail. "He thinks it's all a joke."
The two younger boys were held without bail, while bail for Jones was set at $1 million.
Before the hearing, Edwards' father, James Edwards Sr., said he knew where his son was 95 percent of the time. He said his son was involved in wrestling and football, and was trying to forge the same sort of athletic career as Lane. He was heading into his sophomore year in high school.
Edwards Sr. said Luna was also like a son to him.
