All three were denied bond during their initial court appearances.
Wearing green jumpsuits and chains, Antonio Turner, 17; James Daughtie, 26; and William Omar Jacobs, 22, sat before Augusta Magistrate Judge H. Scott Allen at the Municipal Building.
Daughtie was arrested Thursday in the fatal shooting of Dontrell Kyler in Cherry Tree Crossing. Kyler, 25, who was shot several times, was a passenger in a car with 32-year-old Ozzie Brian Jones, who was wounded. Daughtie faces eight charges, including murder and aggravated assault.
Jacobs is charged with burglary Friday's early-morning break-in at Overstreet's Cumming Road home.
Overstreet shot 20-year-old John E. Howard Jr., of Blythe, who was pronounced dead at Medical College of Georgia Hospital.
After learning of a warrant for his arrest, Jacobs turned himself in.
The judge noted that Jacobs was placed on probation July 1 for a cocaine charge. He also said Jacobs had a criminal trespass and misdemeanor marijuana arrests dating back to 2008.
Allen said, "I find there is a strong likelihood you pose a danger to the community."
Turner was arrested Sunday and accused of detonating three "overpressure devices" made from household chemicals and plastic bottles in the M&M Scott Apartments on Spruce Street.
He is charged with three counts of manufacturing or transporting a destructive device or explosive, reckless conduct and obstruction of a officer.
He questioned the judge about his obstruction charge.
The judge said it was because Turner is accused of walking away from the deputy, and added, "That would be the least of your troubles."
