According to the Times Reporter, the documentary “Vampires in Gem City” was set to expose Dayton as having the second largest vampire coven in the United States and featured the missing person’s case of 26-year-old George Phillip Gall.

It is reported that Gall went missing on October 13, 1994 after getting off a bus near the goth-themed Asylum nightclub.

The bus driver told investigators that Gall walked toward the Asylum nightclub and was never seen again. He was declared dead by the state of Ohio in 2002.

According to Times Reporter, it wasn’t until 2008 that rumors of vampires started after a retired Dayton police officer told The Dayton Daily News that a bartender at the nightclub told him Gall was killed and beheaded for an occult ritual.

It is reported that after Gall’s disappearance in 1994, Williams went to the nightclub undercover and noticed it attracted a large “gothic, vampire-like” crowd. It was while he was undercover that a bartender confided in Williams that Gall’s head was sold inside the club.

Williams told the Dayton Daily News that the bartender gave enough intricate details to make the story believable. Williams also says that Gall’s body was placed in a storm sewer tunnel accessible inside the nightclub. Officers searched for the body but did not find any evidence of the crime, but they did find “occult markings.”

According to Times Reporter, the mystery behind Gall’s disappearance has led to the birth of an urban legend, with many Dayton residents claiming to have seen a headless man approaching them in tunnels to ask where his head was.
