Suspect held in homeless killings

• Police announce the arrest of a 34-year-old man in the two killings


• No further details are immediately available about Aeman Lovel Presley


• Two homeless men were fatally shot three days apart while sleeping on the sidewalk

(CNN) -- A 34-year-old man has been arrested in connection with the killings of two homeless men who were shot three days apart while they slept on the sidewalk, Atlanta police said Friday.

Aeman Lovel Presley was in custody, but police weren't providing further details about his arrest, said Sgt. Greg Lyon.

Presley or his attorneys couldn't be immediately reached for comment Friday.

Atlanta police called the shootings "sinister" because whoever pulled the trigger wasn't expecting to gain from them monetarily.

"A lot of our shootings involve robbery. A lot of our shootings involve someone making good on an old debt or some kind of revenge factor," Atlanta police Detective David Quinn told reporters earlier this week.

"I don't know why someone would shoot two defenseless men."

The shootings happened during Thanksgiving week within three days of each other.

Three days, 3 miles apart

The first shooting took place November 23.

Dorian Jenkins, 42, was fatally shot five times as he slept, wrapped in a blanket, on a sidewalk in downtown Atlanta.

Less than three days later, Tommy Mims, 64, didn't show up as normal at a recycling center where he took cans and other scrap metals to sell.

Mims, known locally as "Can Man" was found dead under a bridge where he usually slept. His body, also wrapped in a blanket, had seven gunshot wounds. He was killed less than 3 miles from Jenkins.

"They never came out of the sleep they were already in," Quinn said. "They weren't fleeing, running. They were asleep when they took these rounds."

Telling details

Police think the killings are related.

The rounds used in both shootings are fairly distinctive: .45-caliber bullets that, according to Quinn, haven't been made since 2010.

They were fired from revolvers, either a Taurus "Judge" or a Smith & Wesson "Governor." That reveals another troubling fact.

"These guns have a capacity of five or six rounds," Quinn said. But Mims, the second victim, had been shot seven times.

"Someone had to reload the gun in order to get seven rounds in him."
