The son of Donald Eugene McCullough and another man have been arrested in the double homicide that occurred Feb. 7 at the Tempie Lane home of the 56-year-old McCullough and his 66-year-old aunt and caretaker Peggy Molden.

Brawny Jarvis McCullough, 31, and Jonathan Michael Henderson, 28, both Villa Rica residents, were arrested Friday by Newton County Sheriff's Investigators, Georgia Bureau of Investigation agents, U.S. Marshals and the Villa Rica police.

According to a press release, the investigation showed a connection between the murders and an incident that took place in Alabama years prior, where the older McCullough, who was paralyzed and in a wheelchair at the time of his death, was shot by a man who had come to his home to discuss a dog. Investigators did not release any further details Saturday.

Both McCullough and Henderson have been booked in the Newton County Detention Center on two counts of murder.

According to The Randolph Leader, an Alabama newspaper, McCullough "was partially paralyzed after being shot in June 2010 while living in the Bethel East community."

The paper reported that GBI investigators were in Randolph County researching the previous shooting, where a man came to McCullough's Alabama home "to inquire about a dog, pulled out a revolver, forced his way in and shot McCullough three times."

The double homicide was originally discovered around 9:30 a.m. Feb. 7 when deputies and emergency medical personnel received a call for help from a medical alert device inside the Tempie Lane home. They could reportedly see one person down inside the home, and once they forced their way inside they found the second person. Tempie Lane is located off Ga. Highway 162.

McCullough worked for a concrete company, according to an obituary in The Randolph Leader. His funeral was held Tuesday in Woodland, Ala. Molden's funeral was held Monday in Decatur, according to her obituary.
