Anthony Joe Jr., a suspect in the fatal shooting of Augusta Symphony cellist David Reader, has been captured, police said this afternoon.

Mr. Joe, 19, who has been sought for more than a month, was caught in Augusta, Lt. Scott Peebles told The Chronicle.

Mr. Joe was wanted on charges of murder and possession of a firearm during the commission of a crime, and was considered armed and dangerous.

Mr. Reader, 26, was found dead May 11 in the driver's seat of his 1998 Toyota Camry with two gunshots to the chest, said Richmond County sheriff's Investigator Brandon Beckman.

The car's motor was still running when it was found at East Augusta Commons in the 400 block of East Boundary, said police, and the victim's cello was still inside the car.

According to affidavits used to obtain search warrants, witnesses told detectives Mr. Reader paid someone at East Augusta Commons to find him some marijuana. When the person never returned with the marijuana or his money, Mr. Reader left but returned about 15 minutes later.

Witnesses told investigators Mr. Reader demanded his money back and he and Mr. Joe began arguing. It soon turned physical, with Mr. Joe punching Mr. Reader through the driver's side window.

Tyreese L. Finey, 16, who was arrested last month on murder charges in the case, began hitting Mr. Reader from the other side of the car, according to court documents.

When a passenger in another vehicle saw what was happening, she yelled at Mr. Joe to stop, according to the search warrant, then saw him pull a handgun from the waistband of his pants and fire inside the car.

Jonathan Aceto, an Augusta Symphony official and violinist, said Mr. Reader had just completed his first season with the group and was considered a very talented cellist.

Mr. Joe had often been in trouble with the law.

According to documents obtained by The Chronicle in a 2004 investigation, Mr. Joe was left alone in December 2001 with 17-month-old Taj'sha Sierra Adams. The infant's aunt and her boyfriend, Anthony Joe Sr., later rushed the baby to the hospital after the child was found gagging in bed, according to a Department of Family and Children Services report. The infant had suffered internal and brain injuries, including damage to her spleen, liver and kidneys, the report stated.

The sealed report was released after The Chronicle made an open records request. Because he was 12 at the time of the death, Mr. Joe's case was handled in Richmond County Juvenile Court. Herbert Kernaghan, the now-deceased judge who presided over the case, refused to let the public or reporters attend any of the proceedings.
