ATLANTA - A man already accused of gunning down two homeless men in their sleep and fatally shooting a hairstylist as she walked to her car now faces charges in the death of a fourth person.
According to CBS affiliate WGCL,investigators say Aeman Lovel Presley, 34, killed Calvin Gholston while he slept at a shopping center outside Atlanta on Sept. 27. Like two of the other victims, Gholston was also homeless, police said.
Police believe Gholston was Presley's first victim, reports the station.
Police already have accused Presley of killing two homeless men in Atlanta, firing multiple times while the victims were wrapped in blankets and sleeping on the sidewalk.
Dorian Jenkins was killed Nov. 23, followed by Tommy Mims on Nov. 26. Investigators have said both homeless men were shot with an elongated .45-caliber bullet - often called a "cowboy bullet."
In their investigation, police emphasized the type of bullet used as they asked the public and law enforcement agencies nationwide for help with the seemingly random shootings of the homeless men.
Jenkins was shot five times and Mims was shot seven times, and police have described it as "overkill."
Presley also faces a murder charge in the Dec. 6 death of Karen Pearce, a hairstylist, in Decatur, just outside Atlanta.
Police said Pearce was shot as she walked to her car after leaving a downtown restaurant. A break in the case came Thursday when a transit system police officer saw Presley pass through a transit station entry gate with paying a fare, authorities said.
He was carrying a loaded revolver and a box of ammunition, officials said.
Police say Presley confessed to killing Pearce, reports WGCL.
No attorney was listed for Presley in online court records Tuesday.
