The twisted murderer killed a student after making him sit in a "death chair" -- then zapped him with a massive bolt of electricity, police said. He is also believed to have rigged up an electric carpet to kill anyone who stepped on it.
The alleged murders took place in the city of Yekaterinburg, in central Russia. The 30-year-old killer -- named only as Dmitry K -- has pleaded guilty to one murder of a 23-year-old man.
But cops fear the power station worker could have carried out many more. The maniac even bragged to detectives that he would admit to other murders if they could find more bodies.
Detective Vladimir Davydov said: "He attacked this victim in his garage. He tied him into his death chair and sent a huge electric charge through his body.
"We are fairly sure that there were many more victims."
Cops suspect he may have taken other bodies to the city outskirts and set them on fire with rubber tyres. One victim is believed to have been killed in front of the sicko's pal.
Police believe he lured his victims to his garage by posting a classified ad on the internet claiming he wanted to buy and sell computer parts. The student was strapped in the chair before Dmitry pressed a button on his computer screen and murdered them, say investigators.
Police found a small power plant installed in the garage which was linked to a PC.
Cops think he murdered at least six between 2008 and 2009.
The 23-year-old student's body was found in a local forest. The remains could only be identified by his teeth but police found fingerprint evidence which linked the body to the power station worker.
The deranged killer said he planned to build other lethal devices to kill his targets. He claimed he had designed one machine which would stop passing cars. One part of it would remotely stop the car's engine. The other part -- resembling a mat -- would electrocute and kill the driver.
He also said he planned to make a device that would erase people's memory with an electro-magnetic ray.
