CARROLLTON, Ga. -- The Carrollton Police Department has made a fourth arrest in the shooting death 13-year-old Nizzear Rodriguez.
A second suspect, Kenneth Wheat, 21, was picked up around 9:30 a.m. Tuesday morning. A third suspect, 24-year-old Jackquline Leann Freeman, was arrested on Tuesday afternoon.
Those arrests came just a day after a 17-year-old Malik Davis was arrested in connection with the murder. Authorities believe Davis and Wheat were in the house when Rodriquez was shot. Freeman is accused of driving Davis and Wheat from the scene. Police do not believe she drove them to the scene.
Both Wheat and Davis have been charged with murder in the death of Rodriguez, who was shot hours after celebrating his 13th birthday, as well as burglary and firearm possession charges.
Freeman is also charged with murder.
A fourth person, 34-year-old Oleida Ward, is charged with making false statements to police. Authorities say there could be more arrests.
Late Monday night, authorities questioned Wheat as a person of interest however, he was released without being charged.
The shooting took place Sunday afternoon in a unit at the Bristol Lakes Apartments on Chancery Lane.
Originally, authorities believed Rodriguez was killed in a drive-by shooting. However, that theory changed Sunday night, as police now believe Davis went into Rodriguez's bedroom and shot him in the head while he was in bed, according to Capt. Chris Dobbs of the Carrollton Police Department.
Police say they believe Rodriguez was not the intended target.
Davis reportedly had past encounters with other residents of the apartment complex. Police have not yet determined if Davis and Rodriguez knew each other.
Wheat was arrested as a teenager for shooting at a car with someone in it. He spent four years in jail and was released in May. Relatives said that Wheat and Davis did know the Rodriguez family. Rodriguez's grandmother used to cut Davis' hair and have Wheat over for dinner.
Authorities said that during interrogations, Wheat asked to speak with Rodriguez's grandmother.
Dobbs said police never had dealings with Rodriguez, who he described as a top-notch student, or the boy's family. Investigators have had dealings with Davis, but never for anything as serious as murder.
The victim was a student at Carrollton Junior High School.
"Nizzear was a wonderful student, well liked and always smiling," principal Dr. Todd Simpson said in a statement. "This is a difficult day for this school and the entire system. Our thoughts and prayers go out to Nizzear's family during this difficult time."
Carrollton City Schools spokesperson Jay Goodman said grief counselors will be available Monday at the system's four schools and nearby Tanner Hospital.
Carrollton City Schools Superintendent Dr. Kent Edwards called it "a somber day."
"There is no preparation adequate for the loss of a child under such circumstances," Edwards said. "We will continue to work with authorities as they work through the investigation."
Carrollton Police confirmed they served a search warrant at the townhouse next to Rodriguez's home Sunday and made several arrests for assaults and possible gang activity.
Both Rodriguez's family and other neighbors said the neighborhood has been in a recent decline due to gangs. Kanisha Osorio, the victim's aunt, said before her nephew was shot, the boy's grandmother had been making plans to move the family because the apartment complex was dangerous.
Some residents told 11Alive's Devin Fehely that they would like to see the community gated as well as an increased police presence.
