PREVIOUS STORY: Two months after the owner of Valley Pawn Brokers was murdered and his business destroyed by fire, the Marion County Sheriff's Office still has not made an arrest in this case, but today we're learning Sheriff Bo Burnett says he believes he knows who did it.

"I feel real good about the suspect we have in custody," Sheriff Burnett said.

Sheriff Burnett said shortly after 72-year-old Jerry Ridge was found dead inside his business, investigators zeroed in on a person of interest.

That person, is now the sole suspect in the case.

"This person is here at the jail on other charges. I can't release this person's name or identification," Burnett said, "This person has been interviewed by my officers and the TBI so, they know."

The name of the suspect will be released by the TBI if a grand jury chooses to formally charge that person.

Without Jerry, the Valley Pawn Broker's shop is no longer in business. The windows are boarded up, and closing signs are posted out front.

Next door, employees at The Chef's Restaurant said they're still in shock.

"When you lose somebody like that, on a spur of the moment boom no warning, you're not prepared for it," said David Berninger.

Jerry's death is the second tragedy the Ridge family has had to endure this year.

The Sheriff's Office is also searching for Jerry's nephew, Wesley Ridge, who went missing in March.

"He's been missing since the first week of March, we did have some leads that came in but everything's dried up so we do have a $15,000 reward if you have information," Sheriff Burnett said, "I'd like to get both cases resolved. I wish I could get them resolved today."

Between the Sheriff's Office and TBI we're told more than 100 pieces of evidence have been sent to the TBI crime lab.

Sheriff Burnett said he hopes this case will be brought before a Grand Jury in August.

PREVIOUS STORY: The Tennessee Bureau of Investigation has identified the body found in the Whitwell pawn shop fire as that of owner Jerry Don Ridge, 72. 

PREVIOUS STORY: Investigators are trying to figure out how a man died in Marion County after discovering his body inside a burning pawn shop. 

It started around 5:00 Tuesday night at Valley Pawn Broker on Highway 28. Crews were forced to shut the road down for hours after determining the fire was suspicious. 

Investigators could be seen through soot-covered windows and broken glass early Wednesday morning processing the scene at Valley Pawn Broker in Whitwell. 

"This was a confined fire, a relatively quick fire, hot and fast and pretty much in a centralized location," Whitwell Police Department Lt. Paul West said.

Crews found a man's body inside and called in the Tennessee Bureau of Investigation and the Bureau of Alcohol, Tobacco, Firearms and Explosives after deeming the fire suspicious. 

"To follow all of these leads you're finding, it's much easier in our case in a small town to call for some help early on and make sure we don't miss anything," West added. 

David Berninger owns The Chef's Restaurant next door to the pawn shop. As soon as he heard about the fire, he worried about his friend, Jerry Ridge. 

He said Ridge has owned the shop for about 10 years and was the only person who worked there. 

"My daughter said she seen his brother go through and try to open the door and smoke boiled out, so the firefighters had to put on their oxygen and walk in," he added. 

Berninger said this isn't the first tragedy that has hit the Ridge family. Police have also been searching for Ridge's nephew Wesley, who has been missing since March. 

"I pray for the family. I know his wife, he was a deacon at First Baptist Church over here and a well-respected citizen of the community," he added. 

The body has been taken to Nashville for an autopsy. No word on what caused the fire.
