Nearly half of Macon-Bibb's homicides from this year remain unsolved, and Sheriff David Davis says that's a little unusual.

Chelsea Beimfohr sat down with Sheriff Davis Thursday afternoon to discuss those numbers and what investigators are doing bring them down.

Since consolidation at the start of 2014, there are 17 unsolved homicides in Macon-Bibb, but 12 of them are from this year alone.

Blue lights and crime scene tape at the site of a homicide are a familiar sight, something people in Bibb County have seen at least 27 times this year.

"This year, we have 12 unsolved homicide cases, which is a little high for us, based on years past," says Bibb County Sheriff David Davis.

Sheriff Davis says since consolidation in 2014, there have been a total of 17 unsolved homicides out of 91 cases.

That's 17 killers who are still on the loose.

"That's a concern, that is a concern to us, and we're certainly putting all our efforts together to finding them," Davis says.

According to Davis, they have "people of interest" in nearly every unsolved case. "We have suspects in many of our unsolved homicides, but we're looking for that one little piece of information that will bring us over the top to be able to get a successful prosecution."

Davis says since 2014, his investigators have solved about 80 percent of Bibb's homicide cases, which is higher than the national average. According to the FBI, 38.5 percent of murders nationwide remain unsolved.

Davis says, "In other years, we've had unsolved homicides at the end of the year, but as time goes on, we're able to develop suspects and make an arrest."

He's confident that are more time passes and evidence is analyzed, several of these cases will be solved, too, but Davis says many people are scared to tell the authorities what they know.

"It's the culture of the streets -- you know the old term, 'Snitches wind up in ditches,'" Davis says.

But Davis says some of these cases can't be solved without the public's help.

"We need that one little piece of information that can tie it all together and somebody has that, says Davis."
