DeKalb County deputies arrested two more men on gang-related charges Friday, contending they were involved in murdering a young man more than three years ago.

Whether sheriff’s deputies scooping up Ramon Naieem Nichols, 28, of Decatur, and Marques Jerome Nicholson, 24, Friday — just hours after the grand jury issued arrest warrants — was a sign of justice delayed or tenacious policing in the March 2012 killing of 19-year-old Derrick Jamal Linkhorn was unclear.

The two men are in the DeKalb County jail on murder and gang charges, however, after Nichols was arrested in Decatur and Nicholson was captured in Austell.

Three men were arrested shortly after Linkhorn’s killing. Marcus Estes, then 18, turned himself in to police in March 19, 2012; and Malcolm Jamall Wilson, then 19, was caught by the DeKalb sheriff’s office’s fugitive squad on March 16, 2012.

Authorities had arrested Antarious Angelo Johnson, then 17, previously. All three have been in jail since March 2012 on murder and gang charges.

“According to our detectives, the motive for this shooting was a dispute,” police spokeswoman Mekka Parish said in 2012 “Detectives were led to the body through evidence in the case.”

Linkhorn was reported missing on March 8, 2012, and his body was found a week later in the storage area of the Southern Pines Apartments on Mountain View Drive. He had been shot.

It’s unclear how long his body had been in the apartment complex.
