Police in Middle Georgia on Monday said they have “a primary suspect” in the deaths of three women and a 2-year-old girl who were believed to have been killed Friday at a mobile home in Perry.

Officers were sent to check on the well-being of a family at Oakhaven Mobile Home Park on Gaines Drive shortly after 6:30 p.m. Friday.

Perry Police Chief Alan Everidge told The Atlanta Journal-Constitution that a relative of the victims called 911 and “said they had not been able to get ahold of them and … wanted us to check and see if everything appeared to be OK. We arrived and we were able to observe at least one person down inside the residence, and then we checked the residence and found all of them deceased.”

He said at least three of the victims appeared to have been stabbed but that their causes of death were pending autopsy.

In a statement over the weekend, detectives identified the slain as Beaulah Robinson, 82; Tuquondea Robinson, 37; Michelle Joiner, 51, and A’laoiah Joiner, 2.

The investigators noted they believed the episode to be “an isolated incident.” The police statement further mentioned that the victims were related and that officials “believe that the suspect knew the family.”

The neighborhood where the killings happened is on Perry’s southwest side, within a block or so of I-75 and less than a mile north of the Georgia National Fairgrounds & Agricenter.

On Monday, Everidge, described the slayings as “probably one of the roughest I’ve ever seen as far as the age spread and the conditions.”

He added, “We’ve got a primary suspect” and “we’re trying to pull things together.”

Everidge did not identify the suspect or divulge how that person might know the victims.
