Wichita ? A British psychic who came to Wichita with a film crew to look into the BTK serial killer case, says the killer is an “ordinary” person.

“I felt he’s either a maintenance man or a plumber, that kind of profession,” said Dennis McKenzie, a clairvoyant from Cambridge, England. “And I’m almost certain that he works for himself.

“He is an ordinary, ordinary person. He would be just an ordinary, nice guy. At least he’s a nice guy 95 percent of the time.”

In a series of letters signed BTK — which stands for “bind, torture, kill” — the killer has claimed responsibility for eight deaths in Wichita between 1974 and 1986. The communications had stopped for more than two decades before resuming this year.

McKenzie, 50, and the film crew toured a couple crime scenes, hoping to gain insight into the identity of the BTK Killer. Bernie Drowatzky, the former lead investigator in the BTK slayings and now the police chief in Kaw City, Okla., drove to Wichita to accompany McKenzie.

The camera was rolling as Drowatzky and McKenzie walked up to a small green house where Anna Williams nearly became BTK’s eighth victim on April 28, 1979. The killer broke into her home but left after growing tired of waiting for her.

Mark Soldinger, a producer and director for Firecracker Films, said the one-hour program probably would air early next year in England as part of a series about extraordinary people.

McKenzie and the film crew spent several days in Wichita.

Before leaving town Tuesday, McKenzie presented his conclusions — including three sketches — to Wichita police. Police declined to comment on his findings.

McKenzie said he made a living acting as a medium between the living and the dead, but he said he thought most people who claimed psychic abilities were faking it.

“I do believe that 85 percent of them are complete charlatans,” he said. “Then there’s that small percent that really can do it.”

McKenzie said he had worked on four criminal investigations, one of which greatly enhanced his reputation in England. On Aug. 4, 2002, two 10-year-old girls disappeared from the village of Soham. After visiting the town, he gave police a series of clues that pointed to the killer.

“Two weeks later, everything I said came true,” he said.
