Four people were found dead Thursday in Cumberland County, on Renegade Mountain. It's something locals say they weren't expecting.
"I mean when this happens in your back yard. You're only looking for deer and bears, you don't expect something like this," John Moore, President of Homeowners Association.
A resident found four people dead in a car on Eagle Nest Road.
Police say it appears they died from gunshot wounds.
The TBI was called in to investigate.
"Until we know what their results are, there are just a lot of questions that we don't know the answer to yet," said Randall York, District Attorney General.
One of those questions is who are the victims?
"We have not positively identified any victims, although we do feel they are local," said Gary McKenzie, Deputy District Attorney General for Cumberland County. "I can tell you we are concerned that there might be individuals that are younger in age, whether they're juveniles or not, we can't confirm that."
McKenzie says this case is an unusual one. He says four murders at once is not something this community sees every day.
"I think in our county we usually only have three or four a year," said McKenzie.
Police say they are still in search of the shooter; however say there is no need for residents in the area to worry.
"There is no need for worry that the community needs to be in fear of a gunman in the area," said Casey Cox, Cumberland County Sheriff's Office.
At this time TBI says they are unsure of the number of gunmen, but say they are looking into a possible lead. The investigation is still ongoing.
