If there's something going bump in the night, Chad Lewis might be the answer to the question of who you're going to call.

Lewis, an Eau Claire resident, is the co-author of The Wisconsin Road Guide to Haunted Locations, which features Green Lake's Dartford Cemetery.

He will present a program entitled 'Wisconsin's Most Haunted Locations' Thursday, July 24 at 6:30 p.m. at the Caestecker Public Library, Green Lake.  The 518 Hill Street library event is free and open to the public.

Lewis, who holds a master's of science degree in applied psychology from UW-Stout, is a full-time paranormal investigator and author for Unexplained Research LLC, which he co-founded in 2004 with business partner Terry Fisk.

The author of the Hidden Headlines book series, Lewis has also co-authored the Road Guide to Haunted Locations book series along with Fisk.

Lewis hosted The Unexplained radio show from 2003-2006, and is the keynote speaker for The Unexplained conferences.  He is a member of the River Cities Paranormal Society - Ghost Hunters Wisconsin.

After graduate school, Lewis was employed as a grant writer for a non-profit organization, doing paranormal research on weekends and vacations.

From the elusive Loch Ness Monster to tracking vampires in Transylvania, Lewis has traveled the globe in search of the paranormal.

The popularity of the second road guide forced Lewis to choose between his career and his growing sideline venture.

"I decided to do investigations," he stated.

The Wisconsin road guide includes the Dartford Cemetery of Green Lake, which has served as the topic of much interest among modern day legend trippers.

Last year, the cemetery was featured in an episode of the Discovery Channel's 'A Haunting' series.

Though Lewis' book says there are children rumored to be buried in the mausoleum, further investigation says otherwise.

According to information obtained from the Dartford Historical Society, the mausoleum is attributed to Jackson Walker, the proprietor of Green Lake's former Rustic House.

Lewis said he plans to talk about how the oral legend differs from the facts, which will be included in the book's second edition.

The haunted-cemetery legend took on a life of its own and was featured on several websites before Unexplained Research was contacted, he added.

Increased public interest in the cemetery legend has led to vandalism, which is something Lewis wishes to mitigate through education and awareness.

"As one who loves history and holds great respect for graveyards, I, too, share the concern of those who are dismayed by the the legend," he told the Green Lake Reporter."

Instead of turning a cold shoulder, Lewis feels the local community should post signs or create flyers stating that the cemetery is indeed the place of legend.

"It should also include the official stance of the cemetery that they believe it is nothing more than a legend and that they would provide the real history of the cemetery and mausoleum," he advised.  "They should also (state) that people are welcome to visit the cemetery...and that those who do should treat it with respect."

"The communities that have used this approach have found that it does drop vandalism significantly, while increasing the number of responsible people--tourist--to the community," he added.  "I would personally invite those who are worried to come to the presentation and speak with me about ways to combat the vandalism and educate the public so everyone can enjoy the cemetery for many years to come."
