JAKARTA, Indonesia - A dead passenger traveled unnoticed for at least half a day on an executive passenger train, an Indonesian newspaper reported Friday.Anxious family members found the body of Edy Haryanto, 55, sitting in a locked lavatory on Thursday afternoon, more than a day after he had boarded with a group of friends in the central Javanese town of Tegal, the Warta Kota newspaper reported.His family became worried when Haryanto didn't get out at the station in Jakarta at the end of the 6-hour journey and his cell phone went unanswered.The body traveled back and forth between Tegal and Jakarta before a janitor told the family he had been unable to clean one lavatory because the door was locked, the report said. The cause of the death was not immediately clear, but Haryanto had recently suffered a stroke, it said.Dina Nurhandayani, the man's 29-year-old daughter, said she planned to file a complaint of negligence with the state-owned train company PT Kereta Api Indonesia.
