A 27-year-old man under arrest for abandoning the body of a 17-year-old girl was served a fresh warrant Sunday on suspicion of murdering her, police in Aichi Prefecture said.

The suspect, Yosuke Naito, a former employee of the municipal government of Okazaki, Aichi Prefecture, was arrested in late August on suspicion of abandoning the victim's body in a wooded area of Toyoake in the same prefecture last November.

The incident came to light when a human skull was found in February and identified as that of Megumi Nekoyama, of Iwakura, Aichi Prefecture, who had gone missing last fall.

According to police, Naito has admitted to murdering Nekoyama, whom he had met through an Internet dating service, and that he had meant to kill her from the outset. He allegedly told investigators he had wanted to see a dead body.

"I got a sense of fulfillment by killing the girl," he was quoted as saying. Police said they confiscated a videotape from his home that shows what appears to be a corpse.

Naito opened a Web site on dead bodies soon after the alleged murder took place, police said, adding he also said that if he had not been arrested he might have killed another woman.

According to the police investigation, Naito met Nekoyama at the Chukyo racetrack in Toyoake at around 7 p.m. Nov. 7. He allegedly strangled her about 40 minutes later with a length of rope he had ready inside a car parked in a vacant lot.

Naito wrapped the body in a plastic sheet and dumped it among some woods in the city, according to police. Records from Nekoyama's cell phone led police to Naito.
