The murder of a woman in downtown Decatur and two homeless men in Atlanta may be the work of a serial killer.

Aeman Lovel Presley is accused of murdering Karen Pearce on Dec. 6 as she left a restaurant in downtown Decatur. Atlanta police announced Presley’s arrest on Dec. 12 in connection with the murders of two homeless men: Dorian Jenkins, murdered on Nov. 23, and Tommy Mims, murdered on Nov. 26.

He was arrested by MARTA police on Dec. 11 while attempting to enter the Georgia State rail station without paying the fare. He also has a prior record. One of his charges is “possession of a firearm by a convicted felon,” according to a report on the Fulton County Jail website. Other charges include willful obstruction of a law enforcement officer and, now, murder.

Decatur Police Sgt. Jennifer Ross said, “On Friday, December 12, 2014, Investigators with the Decatur Police Department obtained arrest warrants for a suspect in the Karen Pearce case.  An arrest warrant for murder was issued for 34-year-old Aeman Presley of Atlanta, who is currently in custody in Fulton County on additional charges. We are actively working with multiple agencies at this time and cannot provide any further information that may jeopardize ongoing investigations.  We anticipate that additional information will be available early next week.”

Decatur Police say that on the night of Dec. 6 Karen Pearce, 44, of Smyrna, Ga., left a local restaurant and was walking close to where her vehicle was parked. Witnesses reported hearing a gunshot in the area before Pearce’s body was discovered on a walkway near a parking deck behind One Decatur Town Center. Decatur Police have been tight-lipped about this investigation, offering few details and declining phone and TV interviews. Today’s news sheds some light on why police have been sparse with details about this case.

Presley also faces two counts of murder in connection with the shooting deaths of two homeless men: Dorian Jenkins, on Nov. 23, and Tommy Mims, on Nov. 26. According to Atlanta Police, on Nov. 23 at 1 pm police found a 42-year-old man near the intersection of Courtland Street and Ralph McGill Blvd wrapped in blankets. The man was unresponsive. It appeared he’d been sleeping on the sidewalk, 10 feet from the road. An autopsy showed he’d been shot multiple times police said.

On Nov. 26 around 9 am, police found a 64-year-old man wrapped in blankets near 386 Northside Drive who was also unresponsive. He was also shot multiple times, an autopsy revealed.

According to WSB-TV, in the murder of the homeless men the suspect used an elongated 45-caliber bullet, sometimes referred to as a cowboy bullet. He’s also a possible suspect in more murders, according to WSB.

MARTA revealed additional details of Presley’s arrest…

On Dec. 11, 2014 at about 11:45 am, MARTA plainclothes officers observed a male unlawfully entering the fare gates at the Georgia State rail station by following behind a patron without paying the required fare. The male resisted arrest and was placed on the ground for safety and was also put in handcuffs. The officers escorted the male suspect to the Five Points station for further investigation. During the course of the investigation, the suspect was found to have a loaded revolver and a box of ammunition on his person. The suspect was charged with Fare Evasion 16-12-120.1(4), Obstruction 16-10-24 and Possession of a Firearm by a Convicted Felon 16-11-131. He was subsequently transported to the Fulton County Jail for further processing.  In the spirit of cooperation with the Atlanta Police Department, which is conducting an ongoing investigation, MARTA will not release any further details about this incident at this time.

Pearce worked at True Salon in Marietta. Her coworkers posted this reaction on the salon’s Facebook page.

We were notified in the last hour by investigators at the Decatur Police Department that an arrest has been made in the murder of our friend and coworker, Karen Pearce. While we are relieved to hear that a suspect is in custody, we are still trying to comprehend this senseless act of violence that took a very special person from our lives. We appreciate the work of the Decatur Police Department, DeKalb County Sheriffs, the Atlanta Police Department and the Georgia Bureau of Investigations. We are confident the suspect in custody will be brought to justice in a timely manner.

So who is Presley?

A Facebook page for a man with the same name says he’s an aspiring actor who attended Stone Mountain High School. The AJC confirmed that Presley is an actor who appeared in two movies. Police officers could not confirm whether the Facebook profile belongs to the man who is now in custody.
