MOORESVILLE, N.C. — A North Carolina man is documenting the stories of some of the most twisted and horrific crimes in America.

Phil Chalmers, a true crime writer, is interviewing serial killers and you can hear their testimonies in his new podcast, “Where the Bodies are Buried.” Chalmers started his career more than 30 years ago by interviewing school shooters, figuring out red flags, and using this information to train teachers and law enforcement.

Now, his attention is focused on interviewing serial killers.

“There hasn’t been a big serial killer project done since like the 70s or 80s. So, I kind of said just like I did with teen killers, to do the same thing with serial killers,” Chalmers said.

He says the interviews aren’t just to learn the “why” behind the murders.

“If the [killers] have nothing to lose, they will confess to unsolved crimes,” Chalmers said.

He also says some of the interviews he’s conducted have helped law enforcement close cold cases.

“We solved a case in Yukon, Oklahoma. A sex worker was killed and her body was dumped. It’s very sad,” he said. “Samantha, we solved her case. We’re looking for bones right now in LaSalle, Illinois.”

Chalmers says the podcast is to give people a look inside the mind of serial killers around the country, but he also knows this could help victims’ families finally gain some closure.

“Even though I’m in the true crime business and I have a podcast and all this, I never forget the pain that this causes. I never forget the victims. They’re always with me,” he said. “So when people don’t know me, it comes off like ‘Oh you’re friends with serial killers?’ They think so, yeah. It’s for a reason. I’m doing it, I have a mission.”

You can subscribe to the “Where the Bodies are Buried” podcast now. Chalmers says he hopes to one day bring his podcast to the small screen in the form of a TV show.
